{"version":"1.0","type":"rich","title":"activity7, question1","description":"This example shows a pie chart visualizing five categories (A–E) with their corresponding numeric values, alongside a color-coded legend and axis labels. It uses a static sample dataset defined in the code. The visualization is built with D3.js v6, using `d3.pie()` to compute arc angles and `d3.arc()` to generate SVG path data. A `d3.scaleOrdinal` with `d3.schemeCategory10` assigns colors, and the chart renders as SVG elements appended to the body.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/61388b0d2a7c46c7baf8aa0116e4c654?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
