{"version":"1.0","type":"rich","title":"activity7_question1","description":"This example shows a pie chart comparing the population of the top ten countries, with each slice labeled by its percentage of the total and accompanied by a color-coded legend. The chart is built using React and SVG, with D3 v5 handling the pie geometry and layout. The code uses `d3.arc` to generate the pie slices, `d3.schemeCategory10` for colors, and `d3.format` for percentage labels. Data is loaded from a remote CSV file via `d3.csv` and processed in the `useData` hook.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f53e49d0a57944fdbddef28972bfed85?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
