We have this upcoming feature from Alerting and AD plugins where we want to document this feature on launch.
This feature will let users create/manage/view Alerting monitors/alerts and AD detectors/anomalies on the Dashboard page from the visualizations (currently only supporting line graphs) shown there.

(feature description relocated here from duplicate ticket 796):
To help address this disconnect between Visualizations and AD, we propose an integrated solution that allows users to quickly create, run and view anomaly results from a Visualization. For certain Visualizations, users can utilize the effort they've already provided to visualize the data they’re interested in (source data, metrics to analyze), and create an anomaly detector on that same data with just a few extra clicks.

What other resources are available? Provide links to related issues, POCs, steps for testing, etc.
