Draw a Windrose

Draw a Windrose

Hi,

does anyone know, how can i plot a windrose?

at this time i use jqplot for my graphics, but i found
no solution to create a windrose like this here:
http://jsfiddle.net/gh/get/jquery/1.7.2/highslide-software/highcharts.com/tree/master/samples/highcharts/demo/polar-wind-rose/

i dont like the licence terms of highcharts.

perhaps anyone have a nice idea.

thx and regard
