Correct typos, change default output extensions and replace invalid characters from node name #2
Conversation
Typo in concentrate option, semi-colons are not accepted in brackets, default extension for grapvhiz files is .gv or .dot.
Grapvhiz does not like dashes in node names, therefore I replace them with underscores

i was using the output.txt to paste into a graphviz renderer. is this change so that you can just render it locally?

To be honest I cannot recall why I made this change specifically. Probably because .gv is a standard extension for Grapvhiz DOT files. Likely I was using another tool that would pick up .gv files and render them.

Yep, .gv is the correct Graphviz DOT files. Graphviz is imported, but not sure if it's on the build yet...

If the output is saved as a .gv file, graphviz library can be used to display it on the screen if using a notebook and can also be used to save it, as a png in this example.
...
raw_entity_relationship_diagram.write_to_file('raw_entity_relationship_diagram.gv')
graph = graphviz.Source.from_file('raw_entity_relationship_diagram.gv')
graph.render('erd_raw', format='png') #Save file
display(graph)
