Hello Christian,

The following SVG will draw a simple pie with one slice slightly exploded.
This is taken from one of the samples that are included with the IBM
SVGView program. You may want to grab the other samples as I also have
exmples of bar charts and line graphs in the package (from
http://www.alphaWorks.ibm.com/tech/svgview)

Here's the SVG to draw a pie...

Subject:  Pie chart




Hi,
I have this challenge here to create an HTML page form XML (sales) data.
That so far is no problem. Whar is a problem that there is a pie chart to
be
included. I've been playing around with SVG using rotate() and paths with
arcs and the like but I haven't found a solution yet to produce a pie
chart.

Does anyone have a hint for me on how to go about doing that?

Thanks in advance,
Christian Schmitt
