{"version":"1.0","type":"rich","title":"Activity 6 task 5","description":"This example visualizes the relationship between age and average body mass index (BMI) using binned bar charts. It loads CDC survey data from a CSV file, calculates BMI from height and weight, and groups ages into bins before aggregating the mean BMI per bin. The visualization uses D3 v7’s `scaleLinear`, `axisBottom`, `axisLeft`, and `bin` APIs to construct axes and histogram bars in an SVG canvas. Styling is applied via CSS classes, with orange rectangles representing the binned averages.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d3303074ce5d4952b245fd615fbd0f79?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
