Contributions summary:Gilles contributed to the `networkx` library by fixing bugs, improving documentation, and enhancing graph algorithms. Their work included addressing a test error related to the availability of SciPy by modifying the `polynomials.py` file. They also updated reference links in the documentation index and clarified the generation number in the `dorogovtsev_goltsev_mendes_graph()` function, adding tests and references. Furthermore, they implemented changes to restrict the `eigenvector_centrality_numpy` function to only operate on connected graphs.
