How to Create a Radar Spline Area Chart
If you’ve found this article, congratulations! Only statisticians seem to know what it’s called. It looks like a big blob in a frying pan.
But once you’ve found out what it’s called, the rest is fairly easy with the jqchart jquery plugin. You can fully customize the chart for however many categories you have and then you inject the data.

jqChart is a one-stop place for all your charting needs with jQuery. Any other kind of chart you could imagine can be generated with the jqchart plugin, including bubble charts, scatter charts, pie charts, financial charts, and even the plain and simple bar charts.
