JavaScript/jQuery PolarChart API
The PolarChart is a UI component that visualizes data in a polar coordinate system.
The PolarChart UI component visualizes data in a polar coordinate system. In this system, each point on a plane is determined by the distance from the center (the point's value) and the angle from a fixed direction (the point's argument). To understand how a chart is displayed in a polar coordinate system, imagine how it would be displayed in a rectangular coordinate system and then round off the argument axis in your mind.
