A radial pie chart visualizes the distribution of music genres by artist gender and type, with each segment's arc length proportional to the total artist count. The visualization fetches artist data from an external JSON file, aggregates genres, and categorizes counts by gender (Male, Female), group, or unknown. Users can filter by country or adjust the number of displayed genres using a slider. Built with D3 v5 and React, it uses a custom `scaleRadial` for the radius, `scaleBand` for angles, and renders as an SVG.
