I am very much impressed and would like to display a similar approach. I work in the safety industry and think this visual would be perfect to help bring awareness to our 2000 field employees. How to go about making what you have; I don't know, but would be grateful if you could direct me in the right way. Feel free to email me directly. Great work. I will be watching this thread.

var options = chart.options;
