To build an ERD (entity-relationship diagram), add one container per table with kind:"erd" and an x/y position, then add each field with add_node (container:<table id>, no x/y) — rows are stacked and the table sized automatically — and join TABLES (never rows) with add_connection using an ERD pair type such as "one_to_many".
