This bar chart shows total rice production for each state in India, using data from the ICRISAT District Level dataset. The visualization aggregates district-level production figures by state, displaying the sums as color-coded bars that reveal regional yield differences. Built with D3 v7, the chart uses `d3.rollup` for aggregation, `d3.scaleBand` and `d3.scaleLinear` for axes, and a `d3.scaleOrdinal` color scheme. Interactive tooltips display each state’s total production on hover, rendered as an HTML overlay with opacity transitions.
