Graphviz
Graphviz is a free, open-source graph visualization software suite developed by AT&T that renders directed and undirected graphs from textual descriptions in the DOT language. It includes command-line tools like dot, neato, and circo that automatically compute node layouts and produce output in formats such as PDF, SVG, PostScript and PNG. Graphviz is widely used by software engineers, data scientists, academics and documentation tools to visualize diagrams, flowcharts, network topologies, dependency graphs and state machines. It is available across Linux, Windows and macOS, and is often integrated into documentation generators, data analysis workflows, and CI/CD pipelines.

1 suggestionThe Graphviz project has announced on its official download page that a native Apple Silicon build (graphviz-arm64.pkg) is "close to having" an installable release. As of May 2026, this appears to still be in preparation rather than fully released. You should check the official Graphviz downloads page at graphviz.org/download periodically — once the native macOS/arm64 package ships, you can download it directly. In the interim, if you have Graphviz installed via Homebrew (the most common installation method for Graphviz on macOS), Homebrew itself will serve the native Apple Silicon build automatically on M-series Macs, so your command-line tools may already be running natively even if you installed them some time ago. If you installed Graphviz directly from an older downloaded package or built it manually, watch for the official graphviz-arm64.pkg release to ensure you get a properly optimized native version.
