===function "piechart"===
This uses the miter joining of border elements in HTML/CSS to draw pie-shaped slices.  I still don't fully understand the code taken from [[Template:Pie chart]] but have made it a bit more comprehensible.  The main improvement so far is that it is resizable and not limited to 10 slices. 

New parameters are

* ''Radius'' (default 100) - radius of the pie chart
* ''nowiki'' - include a nonblank value to read rather than graph the output

To quote the piechart template

* option "thumb" specifies which side of the page the chart is floated to and defaults to <code>right</code>, as with image files. To make the chart appear on the ''left'' side of the page, specify <code>thumb=left</code>.
* "caption" is a string of text that appears on a line just before the legend.
* option "<code>other</code>", if specified, will cause an "Other" item to appear in the legend. ''(don't know if I implemented that)''
* each "label''N"'' is a string of text that appears in the legend entry for a slice. Omitting it will cause a legend entry to not be shown for that slice.
* each "value''N"'' is the percentage that the slice represents. Do ''not'' include the percent sign.  ''(Need to fix that)''  Also note that it is shown in the legend as written (just after the label), without any rounding or other reformatting.
* each "color''N"'' is a [[Web colors|CSS color code or name]].  See [[Module:Plotter/DefaultColors]] for the default values.  This can be overridden with:
* "colorset" - specifies a Module: space file to get a list of color names and values

Note that the nowiki example given at the beginning of Template:Pie chart's documentation doesn't work, but it doesn't work for that template either.   If there was ever some way to specify colors with numbers like 2 or 8, I think it's been forgotten.
