This example visualizes video game review scores for a subset of games using a horizontal bar chart. The chart maps game names to the y-axis with a band scale and scores to the x-axis with a linear scale, rendering red gridlines and score labels. Built with React hooks and D3 v5, it loads CSV data from a GitHub gist, slices it to twenty entries, and renders SVG rectangles via React components. The code directly uses d3.csv, d3.scaleBand, d3.scaleLinear, and d3.max for data processing and scaling.
