As you know, Bob, I’m mildly obsessed with how to display data visually. Displaying data well is tough, especially when you’re talking about complex data. When I have to design a chart for some crazy-ass set of data, I often look at how others have done the same thing, and I keep tabs on blogs that cover chart-making in detail. I also like to collect examples of how to do it badly.
Thankfully, as I’ve mentioned before, the DoD is a great source of bad charts.
Look at that thing! Click on it and behold it in its full splendor! Some of the data is color-coded, but there are multiple secondary labels per color. Those secondary labels are on top of the chart, partially obscuring words and the connecting lines. The light green is unreadable, and the light blue isn’t much better. Most of the nodes in this graph are blocks of text, except when they’re not. I know this is a working draft, and I know the chart’s designers are trying to convey a lot of information, but good grief this is bad.
