On this week’s episode of The PolicyViz Podcast, I’m pleased to chat with Drew Skau and Robert Kosara, who co-authored a couple of papers on how we perceive the quantities in pie charts. Their work centers on how do we perceive quantities in pie charts–is it angle of the slice, size of the circle, length of the arc? We also discuss data visualization research more broadly and upcoming conferences.
