{"version":"1.0","type":"rich","title":"activity 7 , question 2 ","description":"This interactive scatterplot shows the relationship between age and BMI, with a gradient-filled area chart highlighting BMI trends and a dashed hover line tracking values across the x-axis. The visualization includes a tooltip that displays the exact age, BMI, and category (High or Normal) for the nearest data point, using a bisector to locate the closest value. Built with D3 v7, it loads CSV data and renders SVG elements, incorporating vertical gridlines, labeled axes, and smooth curve interpolation via the `curveCatmullRom` generator. Hover interactions are managed through mouse events that update the tooltip position and visibility.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f8b3d390f632420d80db3b08b9885a46?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
