This pie chart displays the percentage distribution of global internet traffic by device, including smartphones, desktop computers, tablets, and smart TVs. It uses D3.js v7 to load data from a CSV file and render the visualization as an SVG. The chart employs `d3.pie()` and `d3.arc()` to generate slices, with labels positioned using a secondary arc generator. A legend on the right uses `d3.scaleOrdinal` with the `schemeTableau10` color palette to map categories to colors.
