{"version":"1.0","type":"rich","title":"Fork of Pie Chart","description":"This fork of a pie chart visualizes energy data from a CSV file, showing CO2 emissions by year. The chart automatically detects categorical and numeric columns, aggregates values using `d3.rollup`, and displays the top 10 categories with an \"Other\" grouping. Slices and labels are rendered as SVG paths using `d3.arc` and `d3.pie`, with a pastel color scale and a legend. Data comes from Energy_CO2.csv with GDP, CO2, energy consumption, and life expectancy fields.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/67ade2a6b1264efb8c3a1e0bb3e831e4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
