{"version":"1.0","type":"rich","title":"Activity7_Question1_1","description":"This example shows a pie chart of programming language usage share percentages, with each category colored via a categorical color scale and labeled with its language name and percentage value. The visualization loads data from a CSV file using `d3.csv`, processes it with `d3.pie` and `d3.arc`, and renders the chart and a legend to SVG. Labels are placed outward from the arc centroids using `arcGenerator.centroid`, and the chart uses `d3.schemeCategory10` for distinct colors. The legend lists each language with its corresponding color and usage share, while the pie slices are semi-transparent with white stroke edges.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d2effdc002d41f4953380c4b05d8161?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
