This pie chart visualizes the top 10 countries by deaths from air pollution in 2020, using a colorful SVG rendered by d3. The chart segments represent annual income data from a CSV file, with each slice’s color and size determined by d3.pie and d3.arc. A legend displays each profession and its corresponding value, formatted with d3.format. The visualization is built with d3.v5, using asynchronous data fetching to load the dataset before rendering.
