{"version":"1.0","type":"rich","title":"Viz1","description":"This example uses a pie chart to display the distribution of COVID-19 cases across different countries, with each slice sized by the total number of cases. It is built with D3 v6, utilizing `d3.select`, `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to render the chart as an SVG. Hovering over a slice triggers a tooltip that shows the specific case count and percentage of the total, calculated with `d3.sum`. The data is loaded from a CSV file using `d3.csv`, and a legend is added with colored rectangles and country labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/51956ba227cc4941ab4b1f730f14ffe6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
