{"version":"1.0","type":"rich","title":"Activity 7.1","description":"This pie chart visualizes sales by product, with each slice sized according to the product's sales value and colored using a categorical color scheme. The visualization is built with D3.js (v7), using `d3.pie()`, `d3.arc()`, and `d3.scaleOrdinal` to generate and style the chart, with an SVG-based legend and labels positioned via arc centroids. Data is loaded asynchronously from a remote CSV file using `d3.csv`, and the chart is rendered entirely through SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b694cf86b5d4e81ba54d2216ae05779?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
