Spider Web chart?

[Richard Gaskin]

A while back (2010) there was a request here for anyone who's made a 
spider web chart - e.g.:
<http://www.texample.net/media/tikz/examples/PDF/spiderweb-diagram.pdf>

I have a need for one myself, and the posts at the time had some useful 
general tips on making charts but nothing on spider web charts specifically.

The trick to this one is the need to translate coordinates outward from 
a centerpoint along a variable number of axes.

Anyone here have such a tool, or other code useful for making one?
