// Package dot implements GraphViz DOT marshaling and unmarshaling of graphs.

// # Attribute quoting
//
// Attributes and IDs are quoted if needed during marshalling, to conform with
// valid DOT syntax. Quoted IDs and attributes are unquoted during unmarshaling,
// so the data is kept in raw form. As an exception, quoted text with a leading
// `"<` and a trailing `>"` is not unquoted to ensure preservation of the string
// during a round-trip.
