I know this is not an easy feature but I love pie charts the are by far the easiest to read and would help people understand some stats easier visually. Might be less confusing for some users. I understand your bar and line graph but have difficulty relating to the plot chart. I am reading your tutorial (which is outstanding to get a better understanding. Thanks to your team for such and excellent app.
