A circular barplot visualizes the distribution of music genres across an artist's albums, fetched from the Wasabi API. Each genre corresponds to a colored arc, with its radial length proportional to the number of song occurrences. The SVG chart uses D3 v7’s `scaleBand` for angular positioning and `scaleRadial` for bar length, drawing arcs with `d3.arc`. Hovering highlights a bar and displays a tooltip, implemented via D3 selections and event listeners.
