A horizontal bar chart displays corn production by state for 2020, using a custom bright teal fill for each bar. The visualization customizes axes by removing default domain lines and tick marks on the y-axis, and modifying the x-axis tick labels to abbreviate large numbers (e.g., converting billions), through d3.axisBottom and d3.format with a custom replace function. The chart is built with d3.scaleBand and d3.scaleLinear, and the data comes from a CSV file.
