Open-source graph visualisation tool for automatically generating flowcharts, network diagrams and structural relationship diagrams.
Graphviz is a classic open-source graph visualisation tool that uses the DOT language to automatically generate directed graphs, undirected graphs, flowcharts and network diagrams. It suits drawing algorithm flows, system structures, knowledge networks, dependencies and model framework diagrams.
Use cases: network diagrams, flowcharts, structure diagrams, dependency graphs, automated drawing
Note: Graphviz suits diagrams with a clear structure; for carefully hand-laid-out illustrations, pair it with Inkscape or diagrams.net.
