Did you roll your own SVG chart lib for this? If not, mind sharing which one you're using? It's very nice.
If you were to make it so I can open a socket or websocket to it (perhaps on a second, internal port) and publish whatever data I want, that'd be all kinds of nifty. That is, make it so I can just start spraying numbers at ws://myhost:5556/Really%20Awesome%20Data and with that a nice auto-scaled chart magically appears in the dashboard.
Edit: Oh, I see a github ribbon. Maybe you'll see a pull request sometime soon...
Edit 2: Anyone wondering about my original question - the charts are built using the D3 project.
