{"version":"1.0","type":"rich","title":"Activity09 question1","description":"This example shows a pie chart visualizing three categories (A, B, C) with their respective values (30, 20, 50) using a static SVG rendering. The chart is generated with D3.js v7, using the `d3.pie()` layout algorithm to compute arc segments and `d3.arc()` to draw the paths with an outer radius determined by the canvas dimensions. A legend maps each category to a color from the `d3.scaleOrdinal(d3.schemeCategory10)` palette. The code also includes text labels for the x-axis and y-axis, though the y-axis label references an undefined `margin` variable.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fa8cfc0619db4c35af8aa2a7250e0776?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
