哪些工具
推荐Graphviz
from https://networkx.org/documentation/stable/reference/drawing.html
we highly recommend that people visualize their graphs with tools dedicated to that task. Notable examples of dedicated and fully-featured graph visualization tools are Cytoscape, Gephi, Graphviz and, for LaTeX typesetting, PGF/TikZ.
