I built a little visualisation tool, using processing, for graphing sensor activity. In this case, I was specifically looking at a photocell. The nature of the data being sensed, in this case, light, informed the way I chose to display the data.
There are three parameters being graphed here: raw data, averaged readings, and the standard deviation between readings.
The circuit is really simple. It's just a photocell hooked up to an arduino board analog in pin. My arduino board communicates serially to my processing app, which then displays the data accordingly.

wow looks cool, you should get an applet up online so we can see it... or maybe a video.
