Mapping Pixel People formulae with graphviz
I had reached the “end” of the Pixel People game sometime ago, but it was not the end of my experiment as yet.
Basically the professions unlock formulae was going to be the base for me to do some link plotting of their relationships. Graphviz works with the DOT file format, which is nothing more than a text file, so it makes for nice shell scripting. Of course there are other awesome helper libraries like afterglow (messed around with it a bit in the past) which make use of the graphviz library to do the final plotting, but being able to plot directly with graphviz also gives us some more flexibility to do whatever we want (most of the time).
Part of the raw file, with the formulae:
mayor mechanic engineer = mayor + mechanic sheriff = mayor + mayor architect = mayor + engineer landscaper = assistant + architect deputy = assistant + sheriff gardener = landscaper + deputy mechanical engineer = mechanic + engineer botanist = farmer + farmer
The code to create the two DOT files (undirected and directed graphs), and to generate the images based on different layout algorithms. Circo, fdp and sfdp layouts weren’t really useful for this kind of graph, so I commented them out.
#!/bin/sh

echo "splines=true;" >> graph.dot

The front part of the digraph DOT file:
digraph pixpple {
overlap=scalexy;
splines=true;
mayor;
mechanic;
mayor -> engineer;
mechanic -> engineer;
mayor -> sheriff;
mayor -> sheriff;
mayor -> architect;
The front part of the graph DOT file:
graph pixpple {
overlap=scalexy;
splines=true;
mayor;
mechanic;
mayor -- engineer;
mechanic -- engineer;
mayor -- sheriff;
mayor -- sheriff;
mayor -- architect;
And some results…
