Behaviour for specialized diagram renderers.

Each renderer implements render/2 which takes a diagram-specific struct and render options, returning a string.

Built-in renderers

• Boxart.Render.Sequence — sequence diagrams
• Boxart.Render.Mindmap — mind maps
• Boxart.Render.PieChart — horizontal bar charts
• Boxart.Render.StateDiagram — state machine diagrams
• Boxart.Render.GitGraph — git branch/commit graphs
• Boxart.Render.Gantt — Gantt charts

Implementing a custom renderer

defmodule MyDiagram do
  @behaviour Boxart.Diagram

  defmodule Model do
    defstruct [:data]
  end

  @impl true
  def render(%Model{} = diagram, opts) do
    # return a string
  end
end
