That isn't a Hubitat thing, it is a standard Zwave thing. Silabs PC Controller (Simplicity Studio) which is the base level software have the exact same map.
I personally don't use that map much, it can tell you if something is communicating, but not how well (signal strength, route changes, etc) things are communicating. For that, the main Zwave Details page is a bit more useful, or use the excellent community app from Tony Fleisher that allows you to dig deeper and sort the various statistics.
