Thank you @hecomp.
For these cases where we don't have metric streams to validate the charts, we'll need to make that apparent and distinguish them from other cases.
Please add a README to the module that includes...

• a link to docs where you sourced the metrics documentation
• either (a) a link to the example that provides the data or (b) a simple statement that this is based on metric names from docs
