Help name the type of Graph I describe!!!

Hello

I have a somewhat complex vision of a graph that I want to make. I want it to look like a stacked bar graph (see example here: http://www.google.com/imgres?um=1&sa...r:25,s:0,i:168)))) with many differnent 'blocks'

However, I want each one of these blocks to be assigned a different width; but for each block to have the same height.

In effect it would look something like this...

[ ]

Any ideas of what this name would be? Or better yet how/ where I can find a software to let me do this?

Thanks

look more like this
