This bar chart displays corn production by state for 2020, using horizontal bars scaled by bushels. The chart customizes both axes by removing default tick lines and the axis domain, and it reformats tick labels to abbreviate large numbers, converting 'G' to 'B'. The visualization uses d3.csv to load data, d3.scaleLinear, d3.scaleBand, d3.axisLeft, and d3.axisBottom to construct the chart, with d3.format for tick labeling, all rendered as SVG.
