# Proximity & Buffer Analyzer

An interactive computational tool designed for urban studies, contemporary sociology, environmental justice, and public policy to audit spatial equity, food deserts, or environmental exposure.

### Features
1. **Haversine Distance Calculations**: Computes exact geodesic great-circle distances between census tracts and targeted features on the earth's surface.
2. **Equity Auditing Engine**: Automatically parses all numerical demographic attributes and compares their average values inside vs. outside radial buffer zones.
3. **Interactive Buffers Map**: Renders an interactive Leaflet map featuring transparent circular buffer overlays, asset/hazard markers, and color-coded census centroids.
4. **Disparity Calculations**: Identifies relative percentage differences for income, race, education, or other attributes to detect structural spatial inequalities.
