Make a Radial Bar Graph in Adobe Illustrator keeping data live

Continuing on from the movie on making a doughnut chart, this movie shows how to make a radial bar graph in Illustrator. Illustrator has some great graph tools but as they were conceived quite a way back they often "need a little help" especially with presenting data in more modern ways. This movie shows how to make a radial bar chart and keep the data live. Note: at around 6:06, when I'm describing the size difference between the polar grid and the chart, I'm actually referring to the way that the chart is drawn, not the grid.
