# `WolframModel.BranchialGraphSVG`
[🔗](https://github.com/sragli/wolfram_model/blob/main/lib/wolfram_model/branchial_graph_svg.ex#L1)

SVG rendering of the branchial graph returned by `WolframModel.branchial_graph/1`.

Each node represents a possible rule match at the current state. An edge
connects two nodes when their matched hyperedges overlap, meaning the two
rule applications conflict (they cannot both be applied without first
resolving the branch).

Nodes are placed on a circle and coloured by rule name. The label shows the
rule name (truncated) and which hyperedges it matched.

## Example

    universe
    |> WolframModel.branchial_graph()
    |> WolframModel.BranchialGraphSVG.to_svg()
    |> then(&File.write!("branchial.svg", &1))

# `to_svg`

```elixir
@spec to_svg(
  %{nodes: [map()], edges: [map()]},
  keyword()
) :: String.t()
```

Returns an SVG string for `branchial_data`.

Options:
- `:width` / `:height` — canvas size in pixels (default `480`).
- `:title` — optional label at the top.
