PyChart is a Python library for
creating high quality Encapsulated Postscript, PDF, PNG, or SVG charts. It
currently supports line plots, bar plots, range-fill plots, and pie
charts. Because it is based on Python, you can make full use of
Python's scripting power. See some examples.
I've used PyChart to draw some real graphs to publish some real
papers (see my SOSP and
TOCS papers for example).
So it's for real!

Here are links to some competitors, in case you don't like PyChart:
Dislin does 3-D plots, but it's not as configurable or as pretty as pychart.
Ploticus inspired PyChart most. It can produce a very pretty output, but
writing a script for Ploticus is incredibly cumbersome.
A long-time favorite of researchers. But its output is not up to
publishing standard, in my opinion.
