A bar chart and overlaid line chart visualize the top 20 Steam games by total reviews, distinguishing total, positive, and negative review counts. The chart uses D3 v5 and React to load TSV data, filter out games with zero reviews, and render an SVG with a horizontal grid, rotated axis labels, and color-coded bars and lines. The code builds the visualization with `d3.scaleBand`, `d3.scaleLinear`, `d3.axisLeft`, `d3.axisBottom`, and `d3.line`, providing an interactive look at review distribution across popular titles.
