{"version":"1.0","type":"rich","title":"activity7_QUE1","description":"This interactive pie chart visualizes tourism revenue distribution by country, with each slice labeled with its corresponding value in billions of dollars and a color-coded legend. The chart is built using D3.js v7 with SVG rendering, employing the `d3.pie` layout, `d3.arc` for path generation, and `d3.scaleOrdinal(d3.schemeCategory10)` for categorical colors. Data is loaded as CSV from a GitHub Gist and aggregated using `d3.rollup` and `d3.sum`. Text labels are positioned using `arc.centroid` with an offset factor.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d5f367ad72884d4598c06166d4669d3f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
