The <strong>Elixir Visualizer<\/strong> transforms Elixir modules, struct definitions (<code>defstruct<\/code>), type specifications (<code>@type<\/code>), and behavior contracts (<code>@callback<\/code>) into clear, interactive architectural diagrams. By parsing data contracts, pattern-matched function signatures, and module dependencies, Elixir developers and system architects can visually inspect functional domain models and OTP application layouts at a glance.<\/p>\n<h2>The Mechanics of Elixir Visualizations<\/h2>\n<p>In VPasCode, Elixir rendering automatically parses <code>defmodule<\/code> definitions, <code>defstruct<\/code> declarations, type specifications (<code>@type<\/code>), and behavior callbacks (<code>@callback<\/code>) into structured diagram cards. Modules render as primary entity blocks, struct fields display access specifications and default values, and module behaviors or usage contracts generate direct relationship lines between visual nodes.<\/p>\n<h3>1. Essential Setup<\/h3>\n<p>To visualize a standard Elixir module architecture, define behavior contracts alongside structs and module implementations. A distributed telemetry monitoring service demonstrates fundamental Elixir behaviors and struct definitions:<\/p>\n            <div class=\"vpascode-viewer-container vpascode-fancy-active\">\r\n                                <div class=\"vpascode-header\">\r\n                    <span class=\"vpascode-lang-label\">Elixir<\/span>\r\n                    <a href=\"https:\/\/www.vpascode.com\/#elixir: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\" \r\n                       target=\"_blank\" \r\n                       rel=\"noopener noreferrer\" \r\n                       class=\"vpascode-fancy-btn\">\r\n                        <svg width=\"14\" height=\"14\" viewBox=\"0 0 24 24\" fill=\"none\" stroke=\"currentColor\" stroke-width=\"2.5\" stroke-linecap=\"round\" stroke-linejoin=\"round\" style=\"margin-right: 8px;\"><path d=\"M11 4H4a2 2 0 0 0-2 2v14a2 2 0 0 0 2 2h14a2 2 0 0 0 2-2v-7\"><\/path><path d=\"M18.5 2.5a2.121 2.121 0 0 1 3 3L12 15l-4 1 1-4 9.5-9.5z\"><\/path><\/svg>\r\n                        <span>Edit Elixir in VPasCode<\/span>\r\n                    <\/a>\r\n                <\/div>\r\n                                <div class=\"vpascode-code-wrapper\">\r\n                    <pre class=\"lang-elixir\"><code data-language=\"elixir\" class=\"language-elixir\">defmodule Telemetry.Reporter do\r\n  @doc \"Behavior contract for metric reporters\"\r\n  @callback report_metric(metric_name :: String.t(), value :: number()) :: :ok | {:error, term()}\r\nend\r\n\r\ndefmodule Telemetry.Event do\r\n  @type t :: %__MODULE__{\r\n          id: String.t(),\r\n          name: String.t(),\r\n          value: number(),\r\n          timestamp: DateTime.t()\r\n        }\r\n\r\n  defstruct [:id, :name, :value, :timestamp]\r\n\r\n  @spec new(String.t(), number()) :: t()\r\n  def new(name, value) do\r\n    %__MODULE__{\r\n      id: \"evt_\" &lt;&gt;
