The document outlines a mobile app called "Health Data Visualization" created by a team called "CodeNinja" for a hackathon. The app plots government health center data on a map of India and allows users to view the data on a map, chart, or table. It also uses a user's current location to find the nearest medical help and lets users refine results based on their medical needs. Screenshots are included to demonstrate the app's visualization and geolocation features.
