If you’ve read this blog before, or heard me speak, then you know that designing data visualization makeovers is one of my favorite activities of all time. I love redesigning pie charts, in particular.
I recently partnered with a group of public health researchers. We were brainstorming different ways to display the number of new HIV infections in each subgroup and as always, there are several correct ways to display these numbers.
We can all agree that 3-d exploding pie charts are pretty rotten. My vote for worst chart? The clustered bar chart. Clustered bar charts aren’t inherently bad, but their overuse is killing me. A report that only contains the same chart type over and over and over, regardless of whether that chart is really the best tool for the job. Let’s explore alternatives to this overused chart. Don’t forget to vote for your favorite alternative at the end of the post.
