{"version":"1.0","type":"rich","title":"Activity7_Question1_PieChart","description":"This pie chart visualizes chocolate sales by product for March, sourced from a CSV file hosted on GitHub. It uses D3.js to load and filter the data, calculating total sales per product with `d3.rollup` and `d3.sum`. The chart is drawn with `d3.pie()` and `d3.arc()`, while an ordinal color scale maps product names to a blue interpolated palette. A custom legend displays each product alongside its percentage of total sales, rendered as an SVG with a flexible HTML layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4a8352ef60e340d8bddceb8585d817f0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
