Description
Using the NC Example from
http://grass.osgeo.org/grass70/manuals/d.vect.thematic.html#examples
one gets:

The file names are indeed different:

From the documentation it seems that currently the module d.vect.thematic works only for polygons (type=area data). For point data there is a module in AddOns d.vect.thematic2. I tried run the module d.vect.thematic2 with a sample of points and everything worked well with no error.

Interesting! The manual even says: "d.vect.thematic2 creates thematic maps from vector features of all types and numeric attributes stored in the attribute table connected to a vector map." (emphasis is mine).
Perhaps time to merge into trunk and enhance/replace d.vect.thematic?

There are two versions:
- d.vect.thematic in trunk (C module)
- d.vect.thematic2 in addons (Python)
Please keep C version in trunk and enhance.

See also [1] which never received any comments. Maybe this discussion should be part of the general GSoC cartography project ?

Still an issue after GSOC 2016?
The bug is in the Python addon, Adam enhanced the C module (still working on merging the changes). So I guess the bug for the addon is still valid.

After Adam's improvements, what is still missing in the C module which exists in the python addon ? As soon as the first is feature-compatible with the latter we should remove the addon, instead of maintaining the two.

the C module can still only work with colors, line width and point size are not implemented there yet.

Replying to neteler:
I see the same message without the '-l' flag and am a bit stumped about where this comes from. In d.vect.thematic.py the only call to d.graph happens if the '-l' flag is set, so this message do not seem to come from the module itself. <wild guess>Could it be the wx0 monitor that tries to call the file after d.vect.thematic itself has closed and erased its temp files ?</wild guess>
