As you'd have access to the height of an image even through HTMLs IMG
property, you could make each bar one colour JPEG/GIF image block and
access that using data from a database to change the height of the block.

I'd imagine the actual value would have to be the top-most location
value minus the height if you want the bottom to stay along a horizontal
line, the values growing upward.
