This bar chart visualizes total rice production across Indian states using data from the ICRISAT District Level Dataset. Each bar represents a state, with height encoding production volume and a custom purple-grey color scale distinguishing states. Hovering over a bar triggers a D3 tooltip showing the state name and cumulative production value. The visualization uses d3.csv for asynchronous data loading, d3.rollup for aggregation, and d3.scaleBand and d3.scaleLinear for axes and positioning, with SVG rendering and event-driven transitions.
