can't generate graph

Hi. Sorry for my late answer.

I think the problem is with your graphviz installation.

The code just creates the graph in a 'dot' file format and then calls graphviz to render it.

If you use the format 'raw' then no rendering is done, the output is just saved into a file. If you use the format 'dot', then the output still will be in a dot format, bud every node will have some layouting info attached.

If you can produce raw or svg files, but have problems with the others, that clearly indicates that the problem is with the graphviz dot command, as the Segfault also indicates that.

Can you try to render a simple graph to see if graphviz fails with it:

graph {
A -- B
}
