Boxart.Render.Mindmap (Boxart v0.3.2)

Copy Markdown View Source

Renderer for mindmap diagrams.

Accepts a Graph.t() from libgraph and renders it as a tree radiating from a central root node. Children branch to the right by default. When the root has many children (>6), the first few overflow to the left.

Vertex labels are used as node text. The root is detected automatically (the vertex with no incoming edges).

Example

graph =
  Graph.new()
  |> Graph.add_vertex("Root")
  |> Graph.add_vertex("Design")
  |> Graph.add_vertex("Code")
  |> Graph.add_vertex("Test")
  |> Graph.add_edge("Root", "Design")
  |> Graph.add_edge("Root", "Code")
  |> Graph.add_edge("Root", "Test")
