Flowchart Layout Optimizer

This skill uses the industry-standard Dagre library to apply the Sugiyama Layered Graph Drawing algorithm to an SVG-rendered flowchart. The goal is to produce a beautiful, easy-to-read diagram where nodes are aligned into logical layers (ranks) and edges follow clean, non-intersecting paths.

💡 When to Use

Use this skill when you have an existing SVG that visually represents a flow, process, or directed graph, but the current node positions and arrow paths are messy, overlapping, or manually placed and hard to follow.

🛠 Prerequisites

The agent must be in an environment where Node.js and the dependencies listed in package.json can be installed and executed.

📝 Instructions for the Agent

1. Install Dependencies: Run npm install in the skill's directory.
2. Graph Mapping (Critical Pre-step): The provided SVG uses position-based routing and lacks unique id attributes on node groups (g.node) and explicit data-source/data-target attributes on edge paths (path).
   • Agent Action: The agent MUST execute a mapping logic before calling the layout script. This is done by instructing the script to use sequential IDs and providing the connection list.

3. Execute Script: Call the run_script tool with the appropriate selectors and the required flow map (passed as a simplified JSON string).

   Required Selectors:

   • node_selector: g.node
   • edge_selector: path[d] (Selects all paths that define edges)

> **Connection Map Generation (Example for Agent):**

> The agent will internally generate a flow map by analyzing the text content of the nodes and the flow:

> ```json

> {
>   "MAINTAINER": ["REQUIREMENTS ENG", "ISSUE ANALYST", "WORKFLOW ENG"],
>   "REQUIREMENTS ENG": ["FEATURE SPEC"],
>   "ISSUE ANALYST": ["ISSUE ANALYSIS"],
>   // ... and so on for all 14 nodes/artifacts
> }
> ```

> *Note: Since the provided SVG has nodes/edges without IDs, the `run.js` script will now handle the sequential ID assignment.*
