The city is a composite of impressions. Beyond the built environment, it is a constantly changing pastiche of associations and experiences—not just of the people who inhabit it, but of the larger community. New York City, in particular, has two realities: the reality of the physical environment, and the reality of the idea—of what the city and its diverse neighborhoods signify. Inseparably intertwined, these two realities constantly continue to inform each other. Pastiche is a dynamic data visualization that maps keywords from blog articles to the New York neighborhoods they are written in reference to, geographically positioned in a navigable, spatial view. Keywords are assigned based on relevance and recency, surrounding their corresponding neighborhoods. The result is a dynamically changing description of the city, formed around individual experiences and perspectives.
