The issue isn't really the city scale then, it's the numbers for the avg house price: http://www.trulia.com/real_estate/San_Diego-California/marke...

http://www.trulia.com/home_prices/California/San_Diego-heat_... breaks it down better, my domain knowledge of SD ends there, I couldn't tell you whether they're showing an accurate pic of what constitutes most people's idea of San Diego.

The circle is definitely scaled correctly though, the ratio of area of the circle to population (1306300 people per 1809 pixels, or about 722 people per pixel) is within the margin of error for my numbers for new york (about 662ppl/pixel), and LA (about 725ppl/pixel).
