Radar Chart
Radar chart (also known as web chart, spider chart, star chart, etc.) is used to display data as circular two-dimensional plots. In the scope of amCharts you can think of radar charts as circular XY charts with a lot of the same concepts applicable throughout.
Key implementation details
We start by creating an instance of RadarChart. The key point when adding axes to a radar chart is using special axis renderers. For the circular X axis (countries in this example) we use AxisRendererCircular and for the value axis (Y) we use AxisRendererRadial. Then we use RadarLineSeries for the actual plot.
