How do you map a city? By sketching a two-dimensional, black-and-white street plan? Through a multi-coloured schematic of bus and underground lines? Or by tracing links which haven’t yet been marked down? By recording a new cultural phenomena, say, or by mapping personal experience, for example an individual’s memories of their neighbourhood or the sounds heard by a blind man on his walk from home to work.? These are questions to consider for the representation of time-space mapping .
The above dynamic map is a visual exploration of where New Yorkers moved in the last decade. It distills more than 4000 moves from over 1700 people, collected in an informal survey by WNYC, a New York based public radio station.
Each circle corresponds to one zip code area. Its size indicates the number of moves to or from the area. Actually, it is consists of two overlaid circles: a red one for people moving out of the area, and a blue one for people moving to the area. So, a small purple circle with a thick blue outline indicates a place where people tend to move and stay, whereas a red outline indicates a less attractive place.
