Score: 5.8/10 (Innovation: 6, Technical: 5, Documentation: 7, Utility: 5)

Hometowns is a privacy-first, client-side web app that maps the area codes of your contacts onto an interactive North American choropleth, revealing where your social network originates geographically. All parsing and visualization happen locally in the browser, with shareable links encoding only per-area-code counts. It's an interesting personal data-viz experiment with a clean privacy story, though its utility is largely personal/novelty rather than mission-critical.

Target audience: curious users, privacy-conscious individuals, frontend/data-viz hobbyists, personal analytics enthusiasts
