This pie chart visualizes the top 10 countries by tourist visits, with each slice labeled with its value in thousands. The chart renders as an SVG using D3 v5, employing `d3.pie` to compute arc angles and `d3.arc` to generate the path segments. Slice colors come from a `scaleOrdinal` mapping, and a legend lists each country with its corresponding color and value. Data is fetched as CSV from a GitHub gist, with tourist counts formatted using `d3.format` for concise display.
