# Bubble
## Auto Bubble
A bubble chart is a scatter chart but with different sized data points. When 3 numeric columns exist a bubble chart will be automatically created.
```sql
-- @title: Auto Bubble
-- @subtitle: Auto generted bubble chart
SELECT
Profit,
Amount,
(CAST(Profit AS FLOAT) / Amount) * 500 as Margin
FROM Sales
WHERE Status = 'Won'
LIMIT 10;
```
