Count of Property Sales on Neighborhood Level in NYC (2003-2023)

Building on the spatial insights from the geo map, I created a tree map to visualize the count of property sales across neighborhoods in NYC from 2003 to 2023. Each block corresponds to a neighborhood, with its size and color intensity reflecting the number of sales. Larger and darker blocks indicate neighborhoods with higher property sale counts, such as Long Island City in Queens or the Upper East Side in Manhattan. Smaller and lighter blocks represent neighborhoods with fewer transactions.
