Related to this, my manually-generated dot-format output contains duplication (both of nodes and of edges). e.g. If I construct a dag like so:
dag = dag_from_strings(["a = b * c", "d = b/c", "e = d * b"])
then the resulting dot file contains:
node139895363613456 [label="b (w=0)", color="black", shape="ellipse", style="filled",
fillcolor="grey"]
node139895363613456 -> {
node139895363615632 node139895361500048 node139895361499984}
twice!
Currently Habakkuk contains code to generate a dot-format file for use with graphviz. However, graphviz has an eponomously-titled python package and it would be better if we used that. We can probably make it optional so as to avoid having a mandatory dependence on graphviz (i.e. habakkuk is still useful, even if graphviz is not installed).
