ER Diagram Generator

Generate entity-relationship diagrams from database schemas or descriptions using Mermaid, PlantUML, or text format.

Usage

Describe your data model or paste your schema, and this skill will generate an ER diagram.

Examples

• "Generate a Mermaid ER diagram for my user-orders-products schema"
• "Create an ER diagram from this SQL CREATE TABLE statements"
• "Visualize the relationships between these 10 tables"

Guidelines

• Include cardinality notation (one-to-one, one-to-many, many-to-many)
• Show primary keys and foreign keys clearly
• Group related entities together for readability
• Include data types for important columns
• Use consistent naming conventions throughout the diagram
