[Mapserver-users] Using MapServer as a general graphing engine

[Armin Burger]

That should be possible at least with MapScript: creating point objects
from the x/y coordinates and drawing them with the 'draw' method using a
class depending on the z value. A bit more limited something similar
might also be possible with the CGI version and 'feature' layers.
