DOT (Graphviz) rendering for Choreo.C4 architecture diagrams.

Produces C4-model-oriented visualisation:

  • Person — ellipse with thick border
  • Software System — rectangle with solid border
  • Container — rounded rectangle with solid border
  • Component — rectangle with dashed border

Relationships are rendered as directed edges with labels. Clusters group containers by their parent software system and components by their parent container.
