# NYC Mobility Equity Dashboard
_Debayan Mandal_

An interactive Voilà + gridstack dashboard analyzing whether **FHV** and
**Yellow Taxi** services are equitably distributed across NYC neighborhoods
relative to demographic baselines.

## Features

- **Pickup & Drop-off choropleth maps** for FHV and Yellow Taxi by month
- **Diverging demographic maps** showing deviation from citywide population baselines
- **Top-10 stats tables** split by service and direction
- **Month slider** to explore Jan–Mar 2025 data

## Data Sources
