Pie Chart Time Series

Split Between Broadcast and Cable Impressions

A lot of data viz nerds hate pie charts, but they can be sometimes be effective if only showing two variables.

In the case of this dataset, stacked bar charts or side-by-side bar charts or even a two line time series might have looked far more cluttered than this experiment using pie charts as points on a time series. Warning: Use with caution, this is an experiment on an enclosed track.
