This rose wind plot visualizes three categorical values—Wii, X360, and DS—as wedges arranged radially around a central axis. Each wedge’s arc length and radial extent encode the corresponding sales total, with concentric circular guides marking quantitative thresholds. Using D3 v6, the code employs `d3.arc()` with `d3.scaleBand` and `d3.scaleLinear` to map angles and radii, while `d3.stack()` structures the data. A custom `d3.scaleRadial` scales the axis ticks. The SVG is hand-positioned via transforms, with labels and a legend added alongside gridlines.
