{"version":"1.0","type":"rich","title":"Histogram of BMI by Age With Brushing","description":"This visualization displays the average Body Mass Index (BMI) of individuals grouped by age, using data from the CDC dataset. A brush tool allows the user to select a range of ages on the horizontal axis, which then filters the data and re-renders the histogram to show more granular age bins for the selected range. The code uses D3 v7 APIs such as `scaleLinear`, `axisBottom`, `axisLeft`, `bin`, and `brushX` to create and update the SVG rendering. The visualization is built with React and displays the data as a series of rectangular bars, with the title \"BMI By Age\" and labeled axes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bced0f0db29a47c394c792bd01185bc0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
