Stuck on jQuery Visualize plugin

Above I have a link to the jQuery visualize function. Basically it is part of:
http://www.filamentgroup.com/lab/upd...esigning_with/ which allows you to graph HTML tables. I have been messing around with it and I got it to work but I want to make a change.

Right now I am using the pie function. You can ignore all of the other ones because I am only calling the pie function on my table. I want to make the pie chart more into a polygon. Basically the only change would be having non-rounded edges for each "slice" of the pie. I have gone through it but I cannot figure out how the pie is being drawn and if I would could even change anything on it to make it in to a polygon. My fear is that that I cannot change the pie into a polygon without completely redoing the math. I am new at this so anyone who could point me in the right direction would be very helpful! Thanks!

EDIT: I am looking specifically at line 194-205.

I think essentially you need to swap the use of arc() with lineTo(x,y) in that section of code.

It should be possible to determine the correct x and y coords as you already have radius, centerx, centery (counter and fraction) - but you may have to revise your trig knowledge a little (as would I).
