Or, the free Open Flash Chart, which uses Flash to render charts, just like
google's does:

And, ofcourse, someone already developed a plug-in for RoR:

http://pullmonkey.com/projects/open_flash_chart

But none of these 3 chart 'components' allow the user to 'zoom in' and
'scroll' the view... I'm still searching for something like this.
Preferably, it would request 'JSON' / 'XML' data real-time as the user
scrolls to or zooms to regions of the chart...  Or did I not read the Google
Chart API docs that well?
