{"version":"1.0","type":"rich","title":"Activity 7","description":"This visualization displays a pie chart of the top 10 movie directors by number of directed films, with each slice labeled by its count and a legend identifying directors. The chart uses D3.js v6’s `d3.pie` and `d3.arc` to compute and render the SVG paths, while `d3.rollup` aggregates the CSV data from a GitHub Gist. A categorical color scale (`d3.scaleOrdinal`) with `schemeCategory10` colors the slices, and the title and legend are appended as SVG text elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1dc584d0ce5c4e8c81b867aa17da28c2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
