This example shows a horizontal bar chart of the top 12 video games by North American sales, with game names on the y-axis and sales values on the x-axis. It uses React state to load CSV data via d3.csv, then renders SVG rectangles scaled by d3.scaleBand and d3.scaleLinear. Custom gridlines and tick labels are drawn manually using d3.scaleLinear.ticks, while axes are positioned with SVG group transforms. The visualization updates asynchronously when data arrives, with a loading state displayed beforehand.
