{"version":"1.0","type":"rich","title":"piechart_rt15","description":"This pie chart visualizes mobile phone sales aggregated by brand, using data fetched from a remote CSV file. The chart displays each brand as a colored slice with a label showing the brand name and total sales, alongside a legend with color-coded entries. Built with D3.js v7, the visualization uses `d3.csv` to load data, `d3.rollup` to aggregate sales per brand, and `d3.pie` and `d3.arc` to generate and render the slices as SVG paths. A categorical color scale (`d3.scaleOrdinal` with `schemeCategory10`) assigns distinct colors, and the legend is constructed manually with styled HTML divs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8863dcd59ab94dbf806c9dc0ab9593d5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
