Visu-NYC Documentation

Visu-NYC is a geospacial visualization application that allows users to see public data from NYC. This app embeds a map component called kepler.gl and has backend functionality to allow users to create accounts and save maps to their profiles.

*The app currently only allows you to view maps of tree count by census tract (neighborhood) and restaurant inspections. More maps to be added!
