{"version":"1.0","type":"rich","title":"Activity 7.1: Area Chart","description":"This area chart visualizes the relationship between screen size and battery life for mobile devices, grouped by category. It uses stacked, semi-transparent areas with a monotone curve to show how battery life varies across screen sizes for each category. The visualization is built with D3 v7, loading CSV data from a GitHub gist and rendering as SVG. It includes axes for screen size and battery life, plus a legend, using `d3.area`, `d3.scaleLinear`, and `d3.schemeTableau10` for coloring.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5c33f807193b45b69aa46a1a97c2559d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
