💡 [FEATURE REQUEST] A ChartView should be able to take two tables/queries as input

[fquellec]

Is your feature request related to a problem? Please describe.
We often need to represent several types of information in one tab during an experience. At the moment we use a numbering for these cases (Ads 1/3, Ads 2/3, ...). But it would be better if we could build Chartviews from multiple queries.

Describe the solution you'd like
In the config of an experience we could provide several queries, resulting on several tables.
