Graph of state median prices

In the last few weeks I saw a graph which I can't find again.

It showed the median prices plotted for all of the states over the last few years in the one graph.

Can anybody recall seeing it and possibly post a link.

Did you see it on this forum or the previous WebBoard forum or some other site? Was it an attachment to a post?
I can't remember where it was, I suspect it was on the web board.
I went through a number of threads, but without knowing the thread I didn't have much luck.
