This workflow extracts data for a given country, aggregates it, and renames the aggregated column to the country name. The country name as a flow variable is created with the String Configuration node. To overwrite a configuration setting with a flow variable, you can use:
- the flow variable button on the side of the configuration setting where existing
- the Flow Variables tab in the configuration dialog
