DOT Graph Preview and ASCII Export
Previewing a Graphviz DOT graph normally requires installing Graphviz locally or using a remote render service. This browser-based tool lets you paste DOT source and immediately see the graph layout as ASCII art — no installation, no account, no upload.
The preview updates automatically as you type (with a short debounce). Switch between layout engines to explore different visual arrangements. The dot engine is best for DAGs and hierarchies. Neato and fdp work better for undirected graphs and network topologies where a circular or force-balanced layout is more readable.
Click Copy to export the ASCII art to your clipboard. The output is tab-safe and wraps correctly in any fixed-width context including GitHub READMEs (code blocks), Confluence pages, Jira comments, and plain email.
How to use
- Paste your Graphviz DOT language graph into the input field on the main tool page.
- Select a layout engine — dot for hierarchical graphs, neato or fdp for force-directed layouts.
- Click Convert to ASCII, then click Copy to paste the ASCII diagram wherever you need it.
