A circular barplot displays five music genres (Rock, Classic, Pop, Rap, and House) as radial bars around a center, with bar length representing each genre's value from a CSV file. The chart uses D3.js v4 with the `d3.scaleBand`, `d3.scaleRadial`, and `d3.arc` APIs to generate SVG paths for each bar. Labels are rotated and positioned around the plot using trigonometric transformations. The SVG rendering adapts text orientation to maintain readability, with a teal fill applied to all bars.
