Tk show words in graph

[fanticla]

I'd like to display in a TK widget textual words in a structure like the following one (I just pooint to an externale image as it is esaier to understand what I mean, the image is in the center):

IMAGE

As I don't want to reinvent the wheel, I'd like to ask if you know some modules which can help me achive this. I've done some search but I just came out with Canvas, which is good, but it means I must do anything by myself, which is fine, but maybe there is already someting out there...

fanticia:

I think you're looking for Tk::GraphViz. It seems to do exactly what you want.

Disclaimer: I've never used it, but I play around with GraphViz every couple of blue moons, and it's pretty nice.

When your only tool is a hammer, all problems look like your thumb.

Another option is the Tk::Cloth; basically an OO Canvas.
