In this project, I tell the story of street trees in NYC, by visualizing multiple features of street trees and their relationship with species, location and street suffixes.
2015 Street Tree Census is conducted by volunteers and staff organized by NYC Parks & Recreation and partner organizations. In the data set, there are tree data collected includes tree species, diameter and perception of health.

In data,
tracts.geo.json: the shape data of the census tract, a geographic division used by the U.S. Census. It can be found at 2010 Census Tracts (to download, see "Export").
num_by_ct.csv: number of street trees in each census tract, divided into 5 status categories (fair, good, poor, deap, stump).
num_by_spc.csv: number of street trees of each species, divided into 5 status categories.
num_by_spc&st.csv: number of street trees of each species and street suffix.
pct_by_st.csv: percent of species in each street suffix.
pop_by_ct.csv: popular species in each tract.
All .csv files are extracted/processed by Tableau from the original data set, so that the data is easier for D3 to read.
