This graph aims to better visualize corpus discrepancies in terms of space - more precisely the overrepration of the Central district (Bund, Nanking Road, etc), and to a lesser extent, the Western district (Race Course) in the International Settlement - depending on timeslices. This graph eventually reveals photographic "topoi" or landmarks in Shanghai. It also reflects difficulties to attribute precise locations to many photos (especially before the 1930s). This graph has been drawn after the related table (See the "Tables" section - Table 171).
