It is only a limited example but gives you some indication how it is done.<div><br></div><div>Robert<br><br><hr id="zwchr"><blockquote style="border-left:2px solid rgb(16, 16, 255);margin-left:5px;padding-left:5px;color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;">Hi Garry,<div><br></div><div>I have created call graphs and similar for my own code using graphviz.</div><div><br></div><div>The dot language is very easy to work with and you can generate SVG using graphviz.</div><div><br>

images from basic line/ellipse/text kind of primitives. we've been<br>
using PIL (Python Imaging Library) for this, but it'd be nicer to do<br>
this in just erlang. ideally i'd like to be able to generate PNG and<br>
SVG output.<br>
<br>
does anyone have any suggestions?<br>
<br>
thanks<br>
