First, we'll see some basic functionality that duplicates other radar chart libraries, but then goes slightly beyond them.

Features to watch out for:

• Rings can be equal-radii or equal-area, with the latter as default.
• Sections can be equal-angle or data-proportional (the number of points in the innermost ring), with the latter as default.
• Sections can be laid out clockwise or counter-clockwise, with the latter being the intuitive default.
• Data point placement is random within its assigned section and ring, which is why they move when you refresh the page.
• The legend can be placed to the right, left, top or bottom of the radar, not placed at all, with "right" as default.
• Data points are "linked" to their legend entries, so both highlight when you hover over either.
• Data points are colour-coordinated with section colours.
• Sections and rings are linked to data points by reference (an id), not number, which is why you can shuffle the sections and rings however you see fit.
• Rotated sections and rings retain their colour and order in the legend. (The data points themselves get re-ordered in the legend - that's a bug, working on it.)
• Data points can overlap, which means you can stuff a lot of data into your chart, if you want to.
