This pie chart displays the relative values of thirteen listed countries, from Japan at 257 down to Singapore at 130, using a diverging yellow-to-red color scale. The chart is rendered as SVG with D3 v6, using `d3.pie()` to compute arc angles and `d3.arc()` to generate the path shapes. Each slice includes a label with the country name and value, positioned via `arc.centroid`. Data is loaded from a CSV file.
