This project generates a PNG file showing the relationship of cards on a Trello board which represent interdependent tasks.

The ruby script graph-from-trello.rb walks a (hardcoded) Trello board that uses the HelloEpics plugin to define parent/child relationships between cards.

make

This will run the ruby script to fetch data from Trello and create the diagram.gv file. It will then run dot to generate diagram.png and open it (using Preview).

Make will only run the script if either diagram.gv or diagram.png is out of date. Use make clean to delete all the diagram.* files, then run make to recreate them.
