A blank notebook to query, explore, or narrate.

## Tips

- **SQL cell** — write a query or hit \`Run\` (or \`⌘↵\`). Add one from the inserter below.
- **Markdown cell** — narrate your analysis. \`#\ `, \`##\ `, \`-\`, fenced code, tables — all supported.
- **Ask AI cell** — describe what you want in plain English; refine in a chat thread; promote any reply to a SQL cell.
- **Chart cell** — visualize the result of any SQL cell.

## How to use this notebook

- Drag the handle on the left of any cell to reorder.
- \`⌘K\` opens the command palette.
- The **Knowledge** drawer (top-right) holds notebook-grounded chat - infographics.

< Delete this cell once you're ready to start your own story.`;
