This pie chart visualizes the distribution of happiness scores across 20 countries, aggregating all remaining nations into an "Others" slice. Built with D3 v6, it uses `d3.pie` and `d3.arc` to generate the segments, `d3.scaleOrdinal` with `schemeCategory10` for coloring, and a custom legend rendering via `d3.select`. The data is loaded through `d3.csv` from a remote Happiness dataset, processed to highlight the top-scoring countries.
