erd-diagram

To generate an ER diagram from Django or SQLAlchemy ORM models, this skill automatically detects your source files and extracts tables, primary keys, and foreign keys to produce Draw.io diagrams using IE notation.

Yes, you can create database diagrams from raw SQL DDL and Prisma schemas; the tool detects migrations and DDL files to extract schema definitions and output mxGraph XML for direct opening in Draw.io.

The best way to visualize many-to-many relationships and associative tables in an ER diagram is using IE notation, which this skill generates to accurately map N:M links, self-references, and logical foreign keys with clear legends.

To handle ER diagrams for large schemas with hundreds of tables, this skill generates a comprehensive overview diagram and automatically creates domain-specific splits targeting roughly thirty tables per diagram to maintain readability.

Yes, this ER diagram generator supports TypeORM, GORM, and Sequelize; it detects your ORM framework to extract unique constraints, indexes, and relationships for comprehensive Draw.io schema visualization.

External references and logical foreign keys are documented separately in generated Draw.io diagrams to ensure accurate schema representation, preventing unresolved links from cluttering the core IE notation diagram.
