Data Visualization - Charts with lots of metrics/colors [closed]

Question

Okay. I'm working on theming some dynamic charts for some proprietary software. Most of the charts are line, column, or stacked column charts. These are all easy to theme because we're only talking like 4 metrics max being displayed in one chart at a time. However, one of the most-used chart types in the software is a pie chart, and these could have 30+ slices at any given time.

I've been given the exciting task of making sure that all charts (including pie charts with 30+ slices) look beautiful and cohesive. I find it nearly impossible to make a pie chart with 30+ slices look beautiful AND scannable, but I'd love to be proven wrong.

Any great examples out there of complex charts with many metrics/colors that work visually AND read well?

Answer 1

Drill down pie charts seem like a good bet. If that won't work, you could group similar items by color and separate items by shade. Seems like that would cover most of your needs.
