A simple data visualization that maps India's postal pincodes to hexadecimal colors, creating a colorful geographic representation of the country's postal system.

This project converts each 6-digit Indian pincode into a hexadecimal color code and displays the corresponding postal areas on an interactive map. Each pincode area is filled with its unique color, creating a vibrant mosaic that represents India's postal geography. Each 6-digit pincode (e.g., 560001) becomes a hexadecimal color code (#560001)
