Urban signatures. The deviations from the regression line in double logarithmic scale are visualized as bars with the height of the bar being the value of the residual. Each color represents a different group of amenity types. We selected 23 representative categories from the amenity types that show a good fit with the population. (A), (B) Deviations from the expected quantity of amenities. Boston exceeds the expected quantities of most public facilities (e.g., libraries and museums) and open spaces while Los Angeles shows negative deviations in most amenity types. (C), (D) Deviations from the expected spatial distribution. Most amenities in Boston are more evenly distributed than expected, whereas in Los Angeles, most amenities are scattered around the city
