{"version":"1.0","type":"rich","title":"Activity 7: Pie Chart","description":"This pie chart visualizes the distribution of smartphone categories from a CSV dataset. The visualization uses D3.js (v7) to compute slice arcs with `d3.pie()` and renders them as SVG paths using `d3.arc()`. A color scale from `d3.scaleOrdinal(d3.schemeTableau10)` distinguishes categories, while a legend and axis labels clarify the data. The chart also includes tooltips with category names and counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/09f61decf25a4c6ea1d929f28d449f73?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
