{"version":"1.0","type":"rich","title":"Activity 7 Question 1","description":"This example displays a pie chart of user age distributions using six predefined age groups from a CSV dataset. Categories are counted from the `user_behavior_dataset.csv` file, and each slice animates with a fade-in transition via `d3.transition`. The visualization leverages `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with `d3.schemeCategory10` for coloring. A custom legend, built with HTML/CSS flexbox, accompanies the SVG chart to label each age group.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/eca2ae4e2ad6412ab1e5e786ac009880?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
