# Excalidraw Diagram Generator

A skill for generating Excalidraw-format diagrams from natural language descriptions. This skill helps create visual representations of processes, systems, relationships, and ideas without manual drawing.

## When to Use This Skill

Use this skill when users request:

- "Create a diagram showing..."
- "Make a flowchart for..."
- "Visualize the process of..."
- "Draw the system architecture of..."
- "Generate a mind map about..."
- "Create an Excalidraw file for..."
- "Show the relationship between..."
- "Diagram the workflow of..."

**Supported diagram types:**
- 📊 **Flowcharts**: Sequential processes, workflows, decision trees
- 🔗 **Relationship Diagrams**: Entity relationships, system components, dependencies
- 🧠 **Mind Maps**: Concept hierarchies, brainstorming results, topic organization
- 🏗️ **Architecture Diagrams**: System design, module interactions, data flow
- 📈 **Data Flow Diagrams (DFD)**: Data flow visualization, data transformation processes
- 🏊 **Business Flow (Swimlane)**: Cross-functional workflows, actor-based process flows
- 📦 **Class Diagrams**: Object-oriented design, class structures and relationships
- 🔄 **Sequence Diagrams**: Object interactions over time, message flows
- 🗃️ **ER Diagrams**: Database entity relationships, data models

## Prerequisites

- Clear description of what should be visualized
- Identification of key entities, steps, or concepts
- Understanding of relationships or flow between elements

## Step-by-Step Workflow

### Step 1: Understand the Request

Analyze the user's description to determine:
1. **Diagram type** (flowchart, relationship, mind map, architecture)
2. **Key elements** (entities, steps, concepts)
3. **Relationships** (flow, connections, hierarchy)
4. **Complexity** (number of elements)

### Step 2: Choose the Appropriate Diagram Type

| User Intent | Diagram Type | Example Keywords |
|-------------|--------------|------------------|
| Process flow, steps, procedures | **Flowchart** | "workflow", "process", "steps", "procedure" |
| Connections, dependencies, associations | **Relationship Diagram** | "relationship", "connections", "dependencies", "structure" |
| Concept hierarchy, brainstorming | **Mind Map** | "mind map", "concepts", "ideas", "breakdown" |
| System design, components | **Architecture Diagram** | "architecture", "system", "components", "modules" |
| Data flow, transformation processes | **Data Flow Diagram (DFD)** | "data flow", "data processing", "data transformation" |
| Cross-functional processes, actor responsibilities | **Business Flow (Swimlane)** | "business process", "swimlane", "actors", "responsibilities" |
| Object-oriented design, class structures | **Class Diagram** | "class", "inheritance", "OOP", "object model" |
| Interaction sequences, message flows | **Sequence Diagram** | "sequence", "interaction", "messages", "timeline" |
| Database design, entity relationships | **ER Diagram** | "database", "entity", "relationship", "data model" |

### Step 3: Extract Structured Information

**For Flowcharts:**
- List of sequential steps
- Decision points (if any)
- Start and end points

**For Relationship Diagrams:**
- Entities/nodes (name + optional description)
- Relationships between entities (from → to, with label)

**For Mind Maps:**
- Central topic
- Main branches (3-6 recommended)
- Sub-topics for each branch (optional)

**For Data Flow Diagrams (DFD):**
- Data sources and destinations (external entities)
- Processes (data transformations)
- Data stores (dat
