Sorry to be That Guy, but:

Your use of rounded borders for the boxes is skewing the correct
perception of the data.  The rounded borders remove more area from the
smaller bars than the from the larger bars, so smaller bars will seem
even smaller in comparison.  In general, never ever try to make
diagrams "pretty" without reading Tufte [1] front to back at least

Other than that, nice work!  I especially like that you show the raw
data next to the bars.

Push the envelope.  Watch it bend.
