{"version":"1.0","type":"rich","title":"BMI by Age","description":"A histogram displays average body mass index (BMI) across age, using orange bars with white strokes and labeled axes. The code loads CDC health survey data via `d3.csv`, computes BMI from height and weight, and bins ages with `d3.bin`. `d3.scaleLinear` maps age and averaged BMI to SVG pixel coordinates, while `d3.axisBottom` and `d3.axisLeft` render the ticks. Axes labels are added manually, and the chart is built with D3 v7 selections and SVG rectangles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c56b74e9186e4cdca9e65371c0cad776?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
