The panel is the main element in Grafana used to visualize metrics from a time-series database such as Prometheus. Each type of panel has its own query editor that allows you to fine-tune the data that you want to visualize.

There are several panel types, including Graph, Singlestat, Table, Text, and Dashboard List. In this book, you use the Graph panel. This is the main panel type in Grafana and it provides a rich set of graphing options.

For more information about the other panel types, see the upstream documentation at:
