Highcharts - Add bar graph to a pie chart

Question

The goal is to try and show a breakdown of a pie chart by displaying bar graphs off of each slice. This way the user can see the sub-values of each slice in a "different way".

Any idea how to add the bars?

EDIT:

Here is a current iteration. The larger the value, the smaller the "innerSize" value for the outer ring.

Answer 1

Have you considered using a "wind rose" chart? It's similar in style and function to what your higher-ups are suggesting. See http://www.highcharts.com/demo/polar-wind-rose in the Highcharts demo page.
