This bar chart displays video game franchise sales figures from a dataset included in the project files, with Mario leading at 330 million units and The Legend of Zelda at 120 million. The visualization uses D3.js version 7.8.5, employing `scaleBand` for the categorical x-axis and `scaleLinear` for the y-axis, while rendering rectangles as marks. Axes are drawn with `axisLeft` and custom axis-label components from the `@curran/axis-labels` package. The chart includes an inner rectangle background and uses data-driven positioning and sizing for each bar.
