Plugin to visualise live data stream

Hi there,

I manage a website for a client whose company deals with Environmental Issue – one such area he is involved in, is in the area of environmental testing of dust particles in the air etc. He takes various readings everyday, and every hour, of the level of dust particles in the air …

He would like to have a page on his website where this data can be visualised in a live data stream through graphs etc, when I say live I mean updated every hour or so or whatever the intervals are. He wants various clients to then be able to login to this page to see the details and readings etc.

If this works there may be other similar pages with other data.

Is there a plugin or some way of achieving this?

Any help greatly appreciated.
Mike
