<div style="font-family: tahoma; color: rgb(0, 0, 0); font-size: 13.3333px; font-weight: 400; font-style: normal;">Thanks for your help. I have tried method 1 to produce bars and pies successfully, and it helped me a lot.</div>
<div style="font-family: tahoma; color: rgb(0, 0, 0); font-size: 13.3333px; font-weight: 400; font-style: normal;">But it would be nice to be able to construct any type of graphics and place them on polygons to visualize some feature.</div>
<div style="font-family: tahoma; color: rgb(0, 0, 0); font-size: 13.3333px; font-weight: 400; font-style: normal;">Can you do that with your SQL method?</div>

<div>Some examples regarding "Construct graphics with SQL" would be great!</div>

<br />
I know three ways to do that, but I guess there must be more ways.<br />
<br />
1) Pie charts and tables with:<br />
<br />
<a href="http://mapserver.org/output/dynamic_charting.html" target="_blank">http://mapserver.org/output/<wbr />dynamic_charting.html<br />
<br />
2) </a>Construct graphics with Javascript support:<br />
<br />
<a href="http://mapserver.org/mapfile/styleitem.html" target="_blank">http://mapserver.org/mapfile/<wbr />styleitem.html</a><br />
<br />
This option requires that You compile the javascript support. That is a little hard to get to work. Had problems to complile V8 support myself last year.<br />
I have seen nice examples in the past and this is on my personal TO DO list to try out, when I get some spare time.<br />
<br />
3) Construct graphics with SQL. This is the way I have solved things myself. What I have done, is to construct circle sectors for instance with spatial sql expressions. I wrap GDAL sql expression with spatialite syntax in VRT files. These can then be used "on the fly" within mapserver or for preprossing of the data.<br />
I could show some examples if any one is interested.<br />
<br />
Actually I heard that someone was doing dynamic SVGs but I don't now the procedure for that.<br />
