About the SQL code visualizer
Each statement is one step. After it runs, the visualizer shows every table, marks the rows that were added, changed or removed, and shows the result of each query. The explanation says what the statement did, including rows a foreign-key cascade changed.
Every run starts with a fresh in-memory SQLite database with foreign keys on, so you can create tables, insert, update, delete, join and group freely.
