This visualization displays the top 15 best-selling video games by global sales, shown as horizontal bars with length encoding sales volume and sequential blue color encoding relative magnitude. It uses React with D3 v5 scales (scaleBand, scaleLinear, scaleSequential) and loads CSV data from a Gist URL. Each bar includes hover effects, a tooltip showing sales in millions, and value labels, with a title, axis label, and grid lines rendered as SVG elements.
