<h2>Description</h2>
<br />
This is an example of JavaScript Chart Polar Axis. The polar chart is used to represent data consisting of multiple variables on a two dimensional circular area using two or more shapes. You can see how to set a radius and an angle slider. The polar setting is set to true and the initial shapes are splinearea.
