This visualization shows global smartphone market share for major manufacturers in 2024 using a pie chart, with Samsung and Apple dominating at over 40% combined. The chart is built with D3 v7, using `d3.pie()` and `d3.arc()` to generate slices, a `d3.scaleOrdinal` with `d3.schemeTableau10` for colors, and SVG rendering. Data loads from a GitHub CSV file via `d3.csv()`, with interactive tooltips on hover and a legend showing each brand's percentage.
