{"version":"1.0","type":"rich","title":"activity7_question1","description":"This example visualizes the distribution of car horsepower across ten manufacturers using a pie chart, with each slice representing a manufacturer and its size corresponding to the car's horsepower value. The visualization is built with React and D3 version 5, using the `pie` API to compute slice angles, `arc` to generate the donut-shaped paths, and `d3.selectAll` for SVG element creation. Data is loaded from a remote CSV via `d3.csv`, and percentage labels and a legend are rendered using D3's `format` and `schemeCategory10` color palette. All marks and text are rendered as SVG elements within a React component.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/22cf3e95d381438793eab66551a0d7a6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
