{"version":"1.0","type":"rich","title":"activity_10","description":"This example displays a pie chart of travel expenses aggregated by traveler gender, using data loaded from a CSV file via a GitHub gist. It shows the proportion of total accommodation and transportation costs attributed to male and female travelers, with a legend and percentage labels for each segment. The visualization is built with D3.js v7, using `d3.csv` for data fetching, `d3.pie` and `d3.arc` for the chart geometry, and a `d3.scaleOrdinal` for color encoding. Text annotations and a legend are rendered directly in SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f9a14f0404214714a1b72e9a864aabbe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
