About

Graphviz DOT Renderer is an AI-built single-page app in the visualization category (graphviz). It opens in your browser, so there is nothing to install. You provide DOT graph code and get SVG graph. Your input is processed on your device and not uploaded. It needs no account. It is a plain tool: no AI model is involved. The source code is public on GitHub (simonw/tools).
