This is a D3.js pie chart visualizing the top 10 U.S. states by population, sourced from a CSV file hosted as a Gist. The chart displays each state’s postal abbreviation as a label on its corresponding slice, with a legend listing full state names and population counts. The visualization uses `d3.csv` for data loading, `d3.pie` for slice geometry, and `d3.arc` for rendering paths, with a `d3.scaleOrdinal` color scheme and SVG text elements for labels.
