Ideas You Should Steal From This Viz (Installment 15)

“All creative work builds on what came before.” —Austin Kleon in Steal Like An Artist.

Today I offer up another steal-worthy interactive viz. This one is from the New York Times. See a snapshot of this interactive map (with some embellishments) above but definitely follow the link to give it a spin for yourself. Now, you may be thinking: “The New York Times is the Grand Poobah of data visualization. I can’t do what they do.” But you can! Actually, what they are doing here is pretty simple and can be done easily with drag-and-drop tools like Tableau.

Here’s what I suggest you steal from this viz:

  • Make it personal. The map allows you to zoom in on an area of interest to you to see how the issue may affect you or those you know.

  • Multiple perspectives. The map provides three lenses on the location of fatal shootings which help you put the data into context:

    • The number of shootings near each block from 2020 to 2023;

    • The change in shootings since 2016-19; and

    • The racial makeup of areas affected by gun violence.

Do Data Dashboards Pay Off?

I haven’t come across much research on the effectiveness of dashboards for organizations. So I thought I’d share this one with you from MIT. Okay, it’s from the for-profit sector. BUT, it does give you something to chew on. Based on a survey of 1,311 companies, the researchers found that those that were better at using data dashboards were also better at other things like innovation and growth. If you are thinking, “Well, that’s correlation rather than causation,” then I’m glad. Maybe these data tips are making an impact.

However, their research does suggest that something about using dashboards could be paying off for companies. Based on their analyses, which included a case study of one company, the researchers suggest that one reason "dashboarding” appears effective is that:

“Everybody in the company gets to see how it is doing against agreed-upon metrics and works together to make course corrections when necessary.”

The process of getting everyone on board with using a dashboard, they note, can take awhile. They also contend that the best dashboards focus not only on what value is created but also on how that value is created. So although their findings are only suggestive, they do jibe with common sense.

Many nonprofits have shifted their data collection to focus on metrics that help to asses their processes and impacts. Fewer, it seems, are effectively using dashboards to look at those metrics everyday and discuss patterns, trends, and benchmarks, and make course corrections along the way.

Creating customized interactive dashboards isn’t as hard as it sounds and can even be created with free applications like Tableau Public. If you’d like to set up a free consultation to explore this idea with me, please do.

How To Present Data More Effectively For Your Audience (aka The Human Mind)

We hear a lot about applying data to action. But for data to make an impact, it must first take a journey through the human mind. Understanding that journey helps us to consume and present data so that the mind can actually see, grasp, remember, and apply it. Here's a preview of the first few slides of my upcoming webinar on this topic: How To Present Data More Effectively For Your Audience (aka The Human Mind).

Is AI Overkill and Wasteful for Nonprofits?

Food for thought. Most nonprofits don’t need AI tools to deal with their data. Using it to calculate a simple average is like “using a bazooka to swat a fly,’ according to Chitra Sundaram in her article Beyond the hype: Do you really need an LLM for your data?* The sixty-second version of her article is: what most for-profit and nonprofit organizations need are clear data visualizations, descriptive analytics (such as trends and KPIs), and user-friendly data dashboards. And we already have excellent tools for these tasks including Tableau, Qlik and Power BI. Moreover, AI tools are resource hogs. We should focus instead on sustainable IT which is about “optimizing resources, minimizing waste, and choosing the right-sized solution.” When is an AI tool worth it? Sundaram says: when you are working with very complex, unstructured data such as text, voice, or images. Not when you are dealing with structured data (i.e. data in spreadsheets and databases) on participants, donors, or financials, as most nonprofits are.

What's Fundamental to Quality Data?

In their Harvard Business Review article How to Make Everyone Great at Data, Thomas Redman and Donna Burbank describe how companies and nonprofits, despite good intentions, get data wrong due to:

  • the way they enter data into databases,

  • perverse incentives around data, and

  • general distrust of data among employees.

How can organizations get data right? Redman and Burbank sum it up as follows:

I can think of no better way to show staff how the data they collect and input influences decision-making than to visualize that data. Show them a chart with a trend and then ask questions like these:

  • Does this trend look right?

  • Do our data entry procedures appear to have affected the data and thus the trend? If so, what can we improve?

  • What concerns do you have about basing decisions on this trend?

  • Assuming the trend is correct, what might we do differently based on what the trend is showing? What other data would help us to make this decision?

The Average Nonprofit Overuses Averages

I’ve warned of the danger of averages before. Yet, I continue to see nonprofits defaulting to averages when they show data about their clients, participants, volunteers, fundraising, etc. So here’s another warning.

The visualization below (which, by the way, is called a bump chart), does a great job of illustrating the danger of averages. In this chart, average wealth is the wealth of a country’s people divided by the size of its population. The median is the middle value when everyone’s wealth is arranged in order. So billionaires have an outsized effect on the average, but the median is less affected by big outliers like billionaires. That’s why the U.S. ranks 4th in average wealth but 14th in median wealth.

Before you share an average with your board or on your website, consider what the median is. If it’s quite different from the average, you might consider showing both the average and the median or just the median.

How To Present Diversity Data (or What To Steal From This Diversity Scorecard)

Reposted from February 2022

Today’s tip is to take inspiration from Chantilly Jaggernauth’s excellent diversity scoreboard displayed below. It shows diversity among employees in a company but can easily be applied to staff or participants in a nonprofit organization.

I suggest you steal the following ideas from Chantilly:

  • Metric Definitions. In a Tableau Conference session, Chantilly shares the pros and cons of the four metrics in the dashboard. See image of the slide below. None of the metrics are perfect. But together they provide an understanding of where an organization is in its diversity efforts. These definitions are not incorporated in the dashboard itself but could be added through a link or in a tooltip (scroll over) feature.*

  • Views of Diversity. The dashboard provides three views of diversity: overall, gender, and people of color (POC). By providing side-by-side charts with these three views, the dashboard allows users to see variations that overall diversity charts obscure.

  • Color Coding. Each type of diversity has its own color, which makes the comparison among overall, gender, and POC easy, even when you scroll down and can no longer see the column headers. Also the comparison groups (non-diversity, male, and non-POC) are represented by the same colors in lighter shades. This approach makes the dashboard easier to understand. Assigning three additional colors for the comparison groups could be confusing and require a color legend.

  • Simple Charts. These are all charts we all know how to read. So the scorecard is accessible immediately to anyone, even if they are not familiar with the data or the organization.

  • Also, note that the dashboard and the slide use different terms for two of the metrics.

Context is King

Reposted from July 2023

This “sketchplanation” elegantly demonstrates the importance of context in understanding anything. Since data visualizations are supposed to help people understand something, we should pay close attention to context when creating them, adding as much context as is needed for others to appreciate what’s going on and act on it. Considering the following charts . . .

Low-context chart

This is your garden variety chart. I see them all the time. Sure, it provides some context by comparing clients served in different zip code areas. But it doesn’t give me enough context to understand if these numbers are high, low, or somewhere in between. This chart needs more context.

Moderate-context chart

This chart is better than the one above. By providing the previous year’s numbers, we can see where there has been increases and decreases and how large and small they were as well as compare the number increases (3) to the number of decreases (1).

Moderate-context chart

This chart, too, allows for better assessment of the numbers than the first chart did. By simply adding a reference line for the goal, we have a better understanding of what’s going on and where we might need to take action. A reference line showing the average number of clients per zip code might also be helpful.

High-context chart

This “small multiples chart”* gives us much more context by showing how the current numbers compare to past years. Consider, for example, the trend for 60601. Just knowing the current and past years’ numbers would not give you an appreciation of the overall upward trend.

*Small multiples chart: a series of similar graphs or charts using the same scale and axes, allowing them to be easily compared

Ideas You Should Steal From This Viz (Installment 14)

“All creative work builds on what came before.” —Austin Kleon in Steal Like An Artist.

Today I offer up another steal-worthy viz that I came across in the Tableau Public Gallery. All nonprofits need to understand and show the demographics of their participants or the communities they serve. This dashboard of South Korea’s demographics uses some good strategies you can apply to your organization’s charts and maps. Keep scrolling to examine the dashboard and see my suggestions on what to steal from it.

Here’s what I suggest you steal from this viz:

  • Heat = Density. The map uses warmer colors to show higher population density and cooler colors to show lower density. This makes finding the big population centers easy.

  • Charts for key demographics. A quick review of the charts on the right gives you a clear understanding of demographic trends over time.

  • Chart title as color legend. Using the chart title to explain the color coding in the chart is a great way to save space on small charts.

I Used Free ChatGPT To Analyze Survey Data. Here's What I Learned.

1. You collect this type of survey data.

Here’s a familiar scenario. You survey your clients, participants, donors, volunteers, etc. and you include some “Other, please specify” options or other “open-ended” questions to better understand respondents’ opinions, experiences, etc.

2. But you don’t know what to do with it.

You collect your survey data but don’t have the time and/or analytical skills to deal with this qualitative data.* Maybe you create one of those horrible word clouds or, even more likely, you just analyze the quantitative data and ignore the qualitative data.

If you had the time and know-how, you might have “coded” the data in order to analyze it. This involves assigning themes to each open-ended survey response in Excel (or the like) or perhaps using one of these free tools.

*Quantitative data is numerical, countable, or measurable. Qualitative data is interpretation-based, descriptive, and relating to language.

3. But what about AI?

You’ve heard that it’s supposed to make tedious, repetitive tasks much easier, and coding survey responses certainly qualifies as both. Could you use the free version of ChatGPT to get this job done? I shared your curiosity and gave it a try. Bottom line: It helped to identify themes to use as codes but it didn’t do all the work for me. For a little longer description of my experience, keep reading.

4. Prepare for AI.

I watched this YouTube Video based on this article to learn how to craft a prompt that would likely get me what I wanted. I also found free survey data on the City of Chicago Data Portal to use for my experiment. The survey asked 43rd Ward residents about “other priorities” for their ward. I thought I could just upload the CSV data file to Chat, but it turns out you need the paid version for that. So I ended up pasting in the survey answers after entering the prompt. Also note that I used publicly available data. You should think twice about entering any type of sensitive data into Chat.

5. Craft the prompt.

Here it is. Yes, it’s long and yes, I say “please,” although I’m not sure if that affected the results!

6. Here’s what happened.

I first tried pasting in the prompt plus the data but that was too long for Chat. So I had to feed the data (all 23 pages) in batches of about 3 pages at a time and despite entreaties to Chat to update the charts based on ALL of the data I shared so far, it only gave me charts for the last batch I had entered, and I had to combine them in Excel. At first I was impressed with the almost instant tables, but I felt my AI assistant wasn’t quite listening to my instructions or just not understanding them. Still, I did develop this list of themes and Chat did code each survey response according to these themes, but I would not feel comfortable relying on these results and would want to possibly combine some of these themes and read through all the responses to see if I agree with the coding.

Data Viz Resources You Should Know: Visual Capitalist

Here’s a new addition to my highly-curated resources list: Visual Capitalist. I occasionally write a 60-second data tip describing a particular resource, including why I think it’s cool. And I link each of these tips to a resources list on my website.

What is it?

Visual Capitalist is an on-line publisher of data visualizations. Their aim is to make the world’s data more discoverable. As the name suggests, the visualizations primarily focus on markets, technology, energy, and the global economy but also on education, healthcare, and the environment using public sources of data including government entities (i.e. U.S. Census data, FRED, etc.), intergovernmental organizations (IMF, World Bank, etc.), or established thought leaders in their respective sectors (think tanks, non-profits, corporations).

Who’s it for?

Anyone who wants to understand or show information on markets, technology. energy, healthcare, education or the global economy. They allow much of their original visual content to be used by others. In many use cases, this can be done for free. (See more info on using their content.)

Who’s behind it?

Visual Capitalist is independently owned, with its founder, Jeff Desjardins, as a majority shareholder.

Why I think it’s cool

Their visualizations can be quite engaging with high production values. You can share them on social media for free. Sign up for a free subscription on any page of their website to get one in your email box each day.

Behold the Heated Bar Chart

I’ve come across this useful chart a number of times and have yet to find a name for it. So I’m giving it one: the heated bar chart. If a bar chart and a heat map had a baby, it might look like this and be even more powerful than its useful parents. This heated bar chart shows months along the horizontal axis and days of the week along the vertical axis. Darker and longer bars on the two bar charts and darker cells on the heat map show when there has been the highest participation in hours. This allows us to examine patterns in participation. We can see, for example, that the relatively high participation in May is being driven by participation on Mondays during that month but that Monday was not a particularly high participation day during other months. We can also see that, overall, participation was lower during the fall months, regardless of day of the week.

This powerful combo chart can be used with many different types of data fields. For example, you might want to create one showing the number of participants from different gender identity and age groups to see if certain gender groups within certain age brackets are not well represented among your participants.

I made this chart with Tableau Public, the free version of Tableau. But this type of chart can be created with any number of applications. For those of you with at least a little Tableau know-how, check out the steps I took in the comic strip below.

Pop Quiz: Guess What This Chart Shows

Reposted from September 2022

Go ahead and make a guess from the options below. Then scroll down to see how your response compares with others’ and what the answer is!

Keep scrolling!

The answer: The decline in child poverty in the U.S.


As reported in The New York Times, “the sharp retreat of child poverty represents major progress and has drawn surprisingly little notice, even among policy experts.” Read the article (and view the detailed line chart) to learn more about the role of government aid in lifting children and families out of poverty.

I share this chart with you—in this way—for a couple of reasons:

1) It’s an engagement strategy you can use. Rather than present a list of stats to your audience, you can engage them in your data by first quizzing them on an interesting, fun, or counterintuitive finding from your data.

2) Bad new bias. Bad news is more likely to be reported than good news, possibly because bad news sells, according to this article citing various research. Perhaps because of that bias, we may be more likely to assume a chart is telling a negative story. This chart is a reminder of the importance of taking a broader view to gain a more balanced understanding of an issue.

Today I offer up another steal-worthy interactive viz that I came across in the Tableau Public Gallery. Scroll down to see what you should steal from it.

Source: Nir Smilga on Tableau Public

Here’s what I suggest you steal from this viz:

  • Small Multiples. To highlight each country and to allow for easy comparisons across countries, Smilga created one small chart per country and placed them alongside each other, aka a “small multiples chart.”

  • Gray comparison trends. While Smilga highlights the trend for the featured country in each chart using color, the trends for other countries are also in each chart but in a light gray. This allows us to easily compare the trend for the featured country to that of others in general.

  • Color distinguishes trend types. Recent downward trends are highlighted in red, and recent upward trends are highlighted in blue.

  • Choose your view. Smilga allows the viewer to customize the view by selecting the number of columns, time period, and countries shown.

Why You Should Know About Calendar Heat Maps

Want to see patterns in participation, fundraising, volunteering, or social media measures across an entire year? A calendar heat map might do the trick.

This is a new addition to a series of tips on different chart types. In each tip, l give you need-to-know information in a format akin to the “Drug Facts” on the back of medication boxes: active ingredients (what the chart is), uses (when to use it), and warnings (what to look out for when creating the chart). The idea is to fill up your toolbox with a variety of tools for making sense of data. And the calendar heat map is a simple tool you can put to good use!

Active Ingredients (What is a calendar heat map?)

As in the example above, a calendar heat map shows a measure across days on a calendar. The measure might be the number of participants, dollars raised, volunteers recruited, social media engagement, etc.

Uses

Calendar heat maps provide a great way to see patterns in a measure over time, particularly if month and day of the week are important factors. For example, such a chart can help you detect whether participation is lagging on Mondays during summer months. In the example above, you can scroll over dates for more information and use the program filter to see participation for the selected program. Here are instructions for creating an interactive calendar heat map with Tableau and in Excel.

Warnings

Depending on your needs, other charts that show change over time may be more useful to you. For example, if you need to more clearly see the amount of change over time, a line graph might serve you better. For other chart types that show change over time, see below.

Fun Fact

Here’s a fun calendar heat map showing more/less common birth dates.
