This pie chart displays the market share of smartphone brands, using percentage labels for slices above 5% and a legend listing each brand alongside its count. The visualization is rendered as SVG using D3 v7, with the `d3.pie()` layout, `d3.arc()` for the path geometry, and `d3.scaleOrdinal` for categorical coloring. Data is loaded from a CSV file via `d3.csv()`, and the chart is positioned with a translated group. The code also adds generic X and Y axis labels, even though no axes are present.
