When following the second example on the readme an error is thrown:

$ ./tm.py --dfd | dot -Tpng -o tm/dfd.png
Format: "png" not recognized.
$ dot -V
dot - graphviz version 2.50.0 (20211204.2007)

Hi,

the version of dot you are using is quite old and you don't mention what OS your are using, so it is difficult to figured out what is causing this.

In Version 3.0 the Graphivz team fixed some issue with building png image. https://gitlab.com/graphviz/graphviz/-/blob/main/CHANGELOG.md?ref_type=heads#300--2022-02-26 So if you want to have a png you will need to fix the problem of GraphivZ on your system.

You can of course also try to build a JPEG, PostScript, or SVG, with -Tjpeg, -Tps or -Tsvg instead of -Tpng.
