This pie chart visualizes the cost of F1 TV Pro subscriptions across different countries, with each slice labeled with its price in US dollars and accompanied by a color-coded legend. The visualization is built using D3.js v5, fetching CSV data from a GitHub gist and rendering it as SVG. The code uses `d3.pie` to compute arc angles, `d3.arc` for path generation, and `d3.scaleOrdinal` to map costs to a fixed palette. The legend is manually positioned, and all text labels use `d3.format` for numeric formatting.
