pygraphiz appears to be deprecated?

pygraphviz looks to be no longer maintained. Would it be worth migrating eralchemy to use graphviz?

#Rendering from dot file using graphviz
from graphviz import Source
Source.from_file(dotfilename)

The format parameter to Source defines the output format and the engine parameter the layout engine (dot, neato etc).

The only place pygraphviz appears to be used is in eralchemy/eralchemy/main.py in the function:

def intermediary_to_schema(tables, relationships, output):
    """ Transforms and save the intermediary representation to the file chosen. """
    dot_file = _intermediary_to_dot(tables, relationships)
    graph = AGraph()
    graph = graph.from_string(dot_file)
    extension = output.split('.')[-1]
    graph.draw(path=output, prog='dot', format=extension)

Same problem here, cannot install eralchemy due to the pygraphviz package

apt install graphviz
pip install eralchemy

If someone is willing to migrate it, I’m not against 😃
