2. In the left pane, select your Database and Schema.
3. Instead of selecting one of the available tables, click New Custom SQL.
4. You are then be prompted for your query. Provide any filters aggregates or joins you want here.
5. Click OK.

With your custom SQL query provided, proceed to Visualizing Data as if the selection were a normal table.
