Dear Community members ,
I have created this in-detailed guide on how to use the Grafana default Test Data (aka TestDB) Data source plugin to get started with Grafana .
It will help to create various visualizations and understand different test seniors by modifying its pre-configured data.
Also, you do not have to do any configuration as this Data source is part of the core plugin and is available in all Grafana versions (open-source, enterprise, cloud) .
I hope this helps
