SQL Lab is Superset's interactive SQL editor:

1. Navigate to SQL Lab → SQL Editor
2. Select your database and schema
3. Write and execute queries
4. Save results as a dataset for chart building
5. Use Jinja templates for dynamic queries:
   SELECT * FROM orders
   WHERE created_at >= '{{ from_dttm }}' AND created_at < '{{ to_dttm }}'

import requests

}).json()
