{"version":"1.0","type":"rich","title":"IRIS Activity 7","description":"This interactive pie chart visualizes total sales aggregated by region from a remote HR dataset. Built with D3.js, it uses the `pie`, `arc`, and `scaleOrdinal` APIs to render proportional slices with a color scheme from `schemeTableau10`, plus a legend. The visualization is fully responsive, sizing to the browser window via `window.innerWidth` and `window.innerHeight`. Data is fetched as CSV and grouped on the fly using a Map reduce before being passed to the chart. The SVG output includes hover effects on slices for user feedback.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7bd61375c5654410b14d01e880ec3910?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
