Lovely idea, fascinating way to visualize demographics.

One comment, and not at all a criticism of the art: I'm not sure if relative property values between neighborhoods really describes how SF is being ripped apart over time; for that, it might be more accurate to graph, say, proportional difference in median rent over the past n years, which might more closely hew to contested neighborhoods (ie, Pacific Heights doesn't usually catch headlines for how much it's changed in the last 5 years).
