If you're curious about:
- what's inside the query response object
- which field type a table calculation resolves to
- how the data object is structured
you might be interested in the Viz Inspector: https://github.com/noahamac/viz-inspector
This visualization outputs to the screen the visualization objects which are accessible via the custom viz api: data, queryResponse, config, and details. You can copy to clipboard and expand/collapse the object.
