The standard library Dot_Graphtree api defines access to our in-memory representation for Graphvix .dot files.
The Dot_Graphtree api is implemented by the dot_graphtree package.
The Dot_Graphtree api source code is in src/lib/std/dot/dot-graphtree.api. The above information is manually maintained and may contain errors.
