GoKawiilGuide breaks down Graphviz's dot, neato, twopi and circo layout engines
A new technical guide explains how Graphviz's four layout engines—dot, neato, twopi and circo—use different algorithms to arrange diagram nodes, from hierarchical ranks to force-directed springs to radial and circular placements. It recommends pairing this knowledge with a browser-based diagram-as-code editor so developers can preview and switch engines to avoid overlapping nodes and crossed lines.
