This project visualizes food prices across different regions of Bangladesh using an interactive map created with Leaflet in R. The map displays the locations of markets, showing the prices of various food items such as rice, lentils, and vegetables. Each circle on the map represents a market, with the size of the circle indicating the price level — larger circles mean higher prices. Users can click on each marker to see detailed information about the market, district, commodity, and price. This helps identify regional price differences and provides a clear, visual understanding of food cost distribution across the country.
