Side by side, and what each lens hides
Same 5.6 million dots. Each map answers one question well and cannot answer the others. Read them together and the argument of the piece is on one screen: the geometry you choose is a claim about the city.
Where it is loud
Shows: a few thousand blocks carry half the complaints.
Hides: who answers, when, and whether the noise or the caller is the constant.
Read the chapterWho answers
Shows: the precinct line decides how fast a complaint is closed.
Hides: why, and what "closed" meant for the person who called.
Read the chapterWhen
Shows: a day city of machines and a night city of music.
Hides: everything that changed across eleven years.
Read the chapter2019 to 2025
Shows: the 2020 jump, and where it landed hardest.
Hides: whether noise grew or complaining did.
Read the chapterWhat kind
Shows: each part of the city has a sound that stands out.
Hides: how loud any of it is, and how the six classes were drawn.
Read the chapterEvery complaint
Shows: 50,000 of the 5.6 million incidents, as filed.
Hides: nothing and everything: a cloud of dots is not yet a map.
