Data Race in parse_dot_data.

12 comment

in function `parse_dot_data`, a global variable `top_graphs` is used. This global variable will be overwritten repeatedly in multithreading situations. It is a data race and may produce unexpected results. https://github.com/pydot/pydot/blob/1270c6d8e7e77e8dbdad460d22d6448658893717/src/pydot/dot_parser.py#L499-L516...
