## What it is
A browser-based editor and renderer for Graphviz (DOT) diagrams, built with viz.js and ACE editor. It supports live editing, rendering via multiple Graphviz engines, sharing graphs via URL or Gist, and a presentation mode.

## Use cases
- edit and preview graphviz dot diagrams in the browser
- render a dot file from a gist or url without installing graphviz
- share a graph definition with a link
- present a graph full-screen without the editor
- export graphviz diagrams as svg or png

## When to choose
- you need to quickly draw or tweak Graphviz diagrams without installing anything
- you want to share a DOT graph via a simple URL
- you need a presentation-friendly view of a rendered graph

## When to avoid
- you need offline rendering or CLI batch processing of many dot files
- you need diagram types beyond what Graphviz supports
- you need collaborative real-time editing

## Facets
- artifact type: application
- maturity: active
- function: editor, data-visualization, developer-tools
- domain: developer-tools, web-development, data-visualization
- platform: browser
- tags: graphviz, dot-language, diagram-editor, online-tool, viz-js, web-server
