{"version":"1.0","type":"rich","title":"Activity7_Piechart","description":"This example shows the global smartphone market share distribution across brands using a pie chart, with each slice representing a brand’s percentage and a color-coded legend listing all brands alongside their values. The visualization loads D3 from UNPKG and uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate the SVG paths, while data comes from a hardcoded array of brand shares. The chart is rendered entirely with SVG elements, and the legend uses `d3.selectAll` to append rectangles and text labels for each brand.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4df6a3dd6d2845b9a4638bed07560950?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
