   After syncing offline with @john-bodley , it seems like we need to think more about 
   
   ### What kind of UI we have in mind on the explore page?
   
   A. Users need to formulate query to get tabular data first, then map the columns from intermediate table to the encoding channels (color, size, length, position, etc.)
   
   B. The controls list encoding channels, which users can put columns/metrics/aggregates from datasource and our engine translates this back into database query + post-query transformation.
   
   ### What operations should be done on back-end/front-end?
   
   For example, group by and aggregates (count,sum,avg,etc.) should leverage database. 
   Transforming table into tree nodes can be done in js.
