r2712 PolarChartView element is the parent that is responsible for showing different chart series
types in a polar chart.
Polar charts support line, spline, area, and scatter series, and all axis types
supported by those series.
\note When setting ticks to an angular ValueAxis, keep in mind that the first and last tick
are co-located at 0/360 degree angle.
\note If the angular distance between two consecutive points in a series is more than 180
degrees, any line connecting the two points becomes meaningless, so choose the axis ranges
accordingly when displaying line, spline, or area series.
The following QML shows how to create a polar chart with two series:
