{"version":"1.0","type":"rich","title":"Pie_chart_activity_9","description":"This pie chart visualizes language usage distribution from a CSV file, with each slice colored by language and labeled interactively through a tooltip showing exact counts in millions. It uses D3.js v6’s `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate SVG paths with hover transitions, alongside a custom legend mapping the color domain. The chart loads data asynchronously via `d3.csv` and positions the pie off-center with a fixed radius, rendering static arcs with animated tooltip opacity changes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/844eb663fd04432f9a3fd8d700aa17aa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
