e16f9a6cc4* toying around with a graph using networkx layouting * basic implementation and documentation of a class for undirected graphs * import graph module into global namespace * add graph module to documentation * poetry: add networkx as a dependency * remove some debug prints * sort all extracted mobjects w.r.t. z_index * add test for z_index (from #327) * more complex z_index test * black * improve imports * use z_index to have edges below vertices * add type hints * rename some tests to make space for graph tests * fix problem with manual positioning * add test * black * new animate syntax * document label_fill_color
