Dynamic text is a panel for Grafana that dynamically renders Markdown based on the query results.
For example, let's say that your data source returns the following data:
|auth||Handles user authentication.||prod||frontend|
You can then write Markdown with placeholders for the data you want to use. The value inside each double brace expression refers to a field in the query result.
The panel renders Handlebars → Markdown → HTML and displays the final result.
