I run Grafana 7.2.0 Open Source Edition and need to embed a website into the dashboard itself. That is, I need a row or two of the usual panels of graphs, and below them embed an external web site that needs to be periodically reloaded.
How can I achieve this? There do not seem to be any relevant plugins at https://grafana.com/grafana/plugins. Is it possible to write a custom panel just for my instance? If so, any pointers about how to start would be appreciated.
