laying out a large graph with graphviz
graphviz, python
Solution
Try this:
sfdp -x -Goverlap=scale -Tpng data.dot > data.png
The `-Goverlap` preserves the layout but uniformly scales things up until there are no more node overlaps. I was able to get a ~77MB PNG that looks like this when you zoom out.
Problem
My daughters have made a game not unlike tic-tac-toe. Of course as I played it with them I started brute-forcing it in my head... So at lunchtime I made a quick little Python script to 'solve' the game. And I wanted to see the results graphically, so I generated a dot file of all legal moves: I've pasted the data here. When I try and render it using `dot`, it takes forever and I abort it after a few hours. If I render it using `neato` or `sfdp` etc, it takes a few seconds or less but the layout is impossible to actually read: ``` sfdp -x -Tpng data.dot > data.png ``` ``` neato -x -Tpng data.dot > data.png ``` I would be happy for the resulting image to be several megapixels. How can I lay out and render such a big graph? I am open to non-dot suggestions, like Python libraries that can do the layout too.
