{"version":"1.0","type":"rich","title":"BMI by Age","description":"This scatterplot displays average Body Mass Index (BMI) by age, using data from the CDC dataset. The visualization bins individual age and BMI records into age intervals, then draws orange rectangles representing the mean BMI for each bin, with the y-axis labeled \"Average Body Mass Index.\" The chart uses D3 v7’s `bin`, `scaleLinear`, `axisBottom`, and `axisLeft` APIs to aggregate and render the data as SVG rectangles. BMI values are computed from weight and height using the formula (weight / height²) × 703.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c89e99e742a641b98ed9a72d8d0d0773?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
