Using external Applications?

[ava]

Hi,

I wrote a script which prints some code into a tiddler. This code is
dot format which can be used to draw a graph of my tiddlers and how
they link together using graphviz. Now I would like to let
automatically create the picture and open it. Is there an easy way to
call an application?

The next steps would be to integrate the graphic into the layout and
to make it interactive. I'll check for this later.

I am thankful for every suggestion.

Bye,

Take a look at the community wiki:

You'd likely require some side of server-side component to serve the
image file ready for inclusion.
As for interactivity, you might use HTML image maps.

Have you seen these projects:

Thanks a lot! I'm now writing a xml file and using HyperGraph to
display it. Seems to be easier in this case.
