This visualization presents a horizontal bar chart of North American video game sales for the top 12 games, sourced from a CSV file. Built with React and D3 v5, it uses `scaleBand` for the y-axis and `scaleLinear` for the x-axis, rendering bars as SVG rectangles. The chart includes tick lines and labels drawn manually. A second, unused component in the same file defines a 3D scatter plot using Plotly, showing North America and Japan sales over time.
