The goal was to produce a picture in a web-environment.

At the moment rpy2 will be used.... maybe there are way to achieve something
like that in this way, but I'm also new to rpy2.

When the graphic could be written to stdout, the calling environment could reead
it from the forked process.

But maybe rpy2 works different.

Any ideas on that on-the-fly creation of pictures?
If there would be no temporary files this would be fine.
That's the reason why I looked for stdout as output channel.
