# `Choreo.Requirement.Render.DOT`
[🔗](https://github.com/code-shoily/choreo/blob/v0.14.1/lib/choreo/requirement/render/dot.ex#L1)

Graphviz DOT rendering for `Choreo.Requirement` diagrams.

Renders requirements as boxes colored by risk, components as rounded boxes,
tests as stadiums, and stakeholders as circles. Relationship edges are
labeled and styled by their type.

# `theme`

```elixir
@spec theme(atom(), keyword()) :: Choreo.Theme.t()
```

Returns a theme for `Choreo.Requirement` DOT diagrams.

# `to_dot`

```elixir
@spec to_dot(Choreo.Requirement.t(), keyword()) :: String.t()
```

Renders a requirements diagram to a DOT string.

## Options

  * `:theme` — `:default`, `:dark`, `:warm`, `:forest`, `:ocean`, or a
    `Choreo.Theme` struct
  * `:direction` — `:tb` (default), `:td` (alias for `:tb`), `:lr`, `:bt`, `:rl`

## Examples

    iex> req = Choreo.Requirement.new() |> Choreo.Requirement.add_requirement(:a, id: "R1", text: "A")
    iex> dot = Choreo.Requirement.Render.DOT.to_dot(req)
    iex> String.contains?(dot, "digraph")
    true
