This radial bar chart visualizes the frequency of song genres across Rihanna's albums, using data fetched from the Wasabi API. Each colored arc represents a genre, with its length proportional to the number of songs. Hovering reveals the genre name, while clicking displays a pop-up list of matching song titles. A separate timeline chart below plots album release dates, with circles sized by time since release. The visualization is built with D3 v4, using `d3.scaleBand`, `d3.scaleRadial`, `d3.arc`, and SVG rendering, with animations for transitions and interactions.
