It's been a while since I attempted to planetize Manhattan on Curbed, but I have a fresh Excel upgrade and went for it.
The size of each sphere (actually the volume) represents the number of sales in each particular market segment in 2010. The distance north/south of the 0% x-axis represents the percent change in year-over-year (2009-2010) average price-per- square-foot above or below the overall change in price-per-square-foot for Manhattan. In other words, all positive changes mean that the neighborhood beat Manhattan, and negative percent changes mean the neighborhoods trailed Manhattan. Manhattan slipped 1.2% year-over-year on a PPSF basis.
The east/west location on the chart means nothing other than trying to spread out the planets, err?neighborhoods so they don't overlap excessively.
Central Park West was off the chart so to speak so I employed a "Curbed Arrow" (a naming technique a la the Ken Burns Effect in Photoshop).
The resulting chart shows the relationship between the neighborhoods by their respective sizes and how they performed, remembering that a shift in the mix toward larger or smaller unit sales may also skew some of the results.
