This visualization displays the top 20 best-selling games in Japan using a horizontal bar chart, with each bar’s length encoding sales figures and game titles on the y-axis. The chart uses React for component management and D3.js scales (scaleBand, scaleLinear) to map data, while SVG rectangles render the bars with red outlines and yellow fills. Data is loaded asynchronously from a CSV file via d3.csv, sorted by sales, and truncated to the top 20 entries. The chart includes custom axes, tick marks, and grid lines drawn as SVG elements.
