Philadelphia Division Map

This project displays a precinct-level election map for Philadelphia using D3.js and TopoJSON.
Division boundaries come from the City of Philadelphia’s Political Ward Divisions dataset, which notes that each division’s four-digit ID’s first two digits represent the ward.

Setup

1. Generate division_map.topo.json using BigQuery and mapshaper (see notes in index.html).
2. Clone this repository and run a local web server:

   npm install -g http-server
   http-server .

3. Open http://localhost:8080 in your browser.

Use the dropdown to switch between metrics (Q–Y) and hover over divisions to view details like reporting status and race results.
