This graphic from SF Gate is a good four years old, well before I knew what an infographic was, but just because it's old doesn't mean it's not interesting. Here we see San Francisco's Golden Gate Bridge and the "sad tally" of 1,218 known suicides by location. Each black square represents a person who has taken his or her life and 128 light poles are used as reference points.
The east side of the bridge, where most of the suicides occurred, has a pedestrian walkway. The first suicide was just 10 weeks after the bridge opened in 1937.
