{"version":"1.0","type":"rich","title":"activity7_task1","description":"This visualization shows smartphone market share as a static pie chart, with each brand’s proportional slice colored and labeled in a side legend. It loads CSV data via `d3-fetch`’s `csv`, parses numeric `MarketShare` values, and generates arcs using `d3-shape`’s `arc` and `pie` generators. The SVG is rendered in a 500x500 viewport, with colors assigned through `d3-scale`’s `scaleOrdinal` and `schemeCategory10`. Legends are manually appended as grouped rectangles and text elements, while the code imports solely the necessary D3 modules rather than the full library.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6c711add54314c3baf53226d49963113?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
