You know the drill: Better charts = better communication = better understanding = better decision making. Whether you’re trying to highlight the most important findings, simplify that lengthy report, or just get someone to open your report in the first place, charts can be one of your strongest communication tools.
Ready to move beyond the typical pie chart or line chart? Today I’m covering 4 awesome charts that are under-used (but extremely useful!) in evaluation.
Social Network Maps
Although social network maps aren’t brand new to evaluation (read about them on aea365 here), I had to mention them because I’m still surprised how many evaluators aren’t using social network maps.
Social network maps help you understand relationships between organizations, people, or even conference attendees. But beware – social network maps aren’t for everyone.

Tree Maps
Tree maps are for hierarchical or nested data, and they’re great for showing part-to-whole patterns.
Here’s an example from Innovation Network’s State of Evaluation research in which Johanna Morariu, Kat Athanasiades and I examined the proportion of nonprofits demonstrating promising evaluation capacities and behaviors:
Can you imagine that same data in a bar chart? It just wouldn’t work; all the relationships between nested variables would be lost.

Dot Plots
Dot plots are similar to bar charts and clustered bar charts (but in many cases, they’re easier to read and a lot less cluttered).
Here’s a 5-minute overview about what dot plots can be used for:
(Better) Bar Charts
And don’t forget about the good ol’ bar chart, your go-to chart for most of your datasets.
But not all bar charts are created equal. It’s no longer acceptable to paste that default draft chart straight into your report; you should expect to spend a few minutes cleaning up every single chart to improve its labeling and overall readability.
Once you’ve mastered the basic bar chart, try your hand at one of these newer variations, like a diverging stacked bar chart, floating bar chart, or small multiples bar chart. The bar chart’s versatility make it the most essential chart for evaluation.
Have you used any of these charts for evaluation purposes? Are there other new-ish charts you think the evaluation world should be aware of? Please share your ideas with the community!
