{"version":"1.0","type":"rich","title":"Assignment2_Question1","description":"This pie chart visualizes the age distribution of a population, with each slice labeled by age group and its percentage shown in a text tooltip on mouseover. The chart is built with D3.js v3, using `d3.layout.pie` for the pie layout and `d3.svg.arc` for the arc paths and hover geometry. The visualization reads data from a CSV file containing age categories and population counts, and the slices expand slightly on hover to highlight the selected segment.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd5d96d3f97646d4b8ae3382aeffcc12?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
