The primary struggle with dashboard development is not identifying the right key performance indicators, building the graphs in your favorite software, or even getting people excited about the idea of using a dashboard. That’s all a cake walk compared to managing people and their reactions to the dashboard. Let…
Pick a color, any color. You know how this game goes. You pick a color, your friend opens and closes the fortune teller, spelling out the name of the color you selected. You pick a number from the visible choices, your friend opens and closes the fortune teller, until you…
Here’s the thing: The scale used on each axis must have equal intervals. It’s an easy mistake to make. Excel automatically spaces your intervals and labels equidistant from one another but it is assuming that your intervals actually are equidistant. In this graph, that’s not the case. We are missing…

Here’s how to make them more effective. Diagrams come in many different flavors – mind maps, concept maps, flow charts, and so on – but at the core, they are all visualizations of how themes relate to one another. As ubiquitous as diagrams are, they have some significant shortcomings.
When Jenny Lyons and I were pulling together the revised chapter on Qualitative Visualization in Effective Data Visualization, 2nd edition, we ended up ditching this section on dendrograms. In the list of most-likely-to-use qualitative visuals, this one is probably not in anyone’s top ten. But we still wanted to…
