{"version":"1.0","type":"rich","title":"Fork of question 3(Task 2)","description":"This stacked bar chart visualizes the proportion of smartphone app usage across six age groups, from 18-24 to 65+, with each bar segment representing a category such as Social Media, Games, or Productivity. Built with D3 v7, the visualization uses `d3.stack()` to compute the stacked series from the `phones.csv` data and renders them as SVG rectangles. A linear `d3.scaleLinear` maps the usage proportions (0–1) on the x-axis, while a band scale positions the age groups vertically. Color encoding via `d3.scaleOrdinal` distinguishes the app categories, and an interactive legend lists each type alongside its corresponding color.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c7f58e1716b4be3b7027e40a746aea2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
