Clarity.Vertex.GraphShapeProvider protocol (Clarity v0.5.1)

Protocol for providing graph shape information for vertices.

This protocol allows vertices to specify their visual shape in graph visualizations using Graphviz DOT notation.

Summary

t()

All the types that implement this protocol.

shape(vertex)

Returns the shape to be used for the vertex in graph visualization.

@type t() :: term()

All the types that implement this protocol.

@spec shape(t()) :: String.t()

Returns the shape to be used for the vertex in graph visualization.

This is used to determine how the vertex will be rendered in the graph using Graphviz DOT shape names (e.g., "box", "circle", "component").
