{"version":"1.0","type":"rich","title":"Fork of Activity_7_Q2","description":"This visualization displays the relationship between age and BMI, using a gradient-filled area chart with interactive hover effects. It highlights data points categorized as \"High\" or \"Normal\" BMI, and the hover interaction reveals a tooltip with age, BMI, and category details. Built with D3.js (v7.8.5), the code fetches a CSV from a GitHub gist and uses scales, axes, gridlines, and a Catmull-Rom curve for smoothing. An invisible overlay rectangle enables mouse tracking, which drives the tooltip, a dashed hover line, and a marker circle.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a33e2d69bc094785bf0a7eae9017b763?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
