Export DOT Graph as Text (ASCII Art)

When you need to share a graph diagram in a context that does not support images — a code review comment, a CLI tool's help text, a plain-text report, or a README section that must degrade gracefully — exporting as ASCII text is the practical solution.

This tool converts any Graphviz DOT graph to a text representation using box-drawing characters. The result is a self-contained string with no dependencies on image hosting, external CDNs, or browser rendering capabilities. It displays identically in any monospace font.

Supported DOT features: digraph and graph declarations, node labels, edge labels, edge chains (a -> b -> c), and the rankdir attribute. Copy the text output and paste it wherever plain text is accepted.
