{"version":"1.0","type":"rich","title":"6-piechart","description":"This visualization shows the distribution of billionaires across categories using a pie chart, with each slice labeled and a legend identifying the categories. The chart is rendered as an SVG element, sized at 600 by 600 pixels, and uses D3.js (v3) APIs such as `d3.select`, `d3.csv`, `d3.rollup`, `d3.pie`, `d3.arc`, and `d3.scaleOrdinal`. Data is loaded from a CSV file hosted on a GitHub gist, aggregated by category, and visualized with a color scheme from `d3.schemeCategory10`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bf3ca1370dbb436e9c67f3407ed882fc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
