I think it's possible to use LaTeX for this, as long as you're
willing to provide the document basis, put an \include for the
drawing contents and then have a small processing script that
generates this file. There is some LaTeX document class that
supports graphs, I think. The output would be PS or PDF.

For manual work, xfig can be used, but I'm not sure if it can
be "remote controlled" by a data file.
