Loop on Groups of Data

This workflow loops on a list of unique data groups. In this case the data groups are identified by country.
This workflow implements the same task as the workflow named "Loop on List of Values", but in a more efficient manner.

Here we use a single loop start node to isolate the list of unique countries and to loop on them to calculate the statistics for each country: the Group Loop Start node.
