This pie chart displays browser market share percentages, with each slice colored via a categorical scale and a legend identifying the browser names. It uses D3 v7 with `d3.pie` and `d3.arc` to generate the SVG paths, and `d3.csv` to load the remote dataset. Hovering over a slice reveals a tooltip showing the browser and its exact share, while the chart includes a bold title and white stroke separators between slices.
