Auto update of graphs

[Quaxo76]

I noticed that the numeric temperature value updates automatically, but the graph doesn't. It would be nice to have it update automatically - in real time or even just every x minutes. That would allow us to leave a browser window open, with a constantly up-to-date graph being shown. I understand why some people would need the current behavior; so maybe this could be made user-selectable, maybe with an "auto-update" checkbox near the graph itself?
