{"version":"1.0","type":"rich","title":"Activity 6_5_Histogram_Vizualization","description":"This histogram visualizes the average Body Mass Index (BMI) grouped by age, using a dataset loaded via D3's `csv` import. The chart employs D3 v7 APIs such as `scaleLinear`, `bin`, `axisBottom`, and `axisLeft` to bin the data, compute per-bin averages, and render axes and pink rectangular bars as SVG. The visualization also uses custom `g.selectAll('rect').join('rect')` appending and includes axis labels with rotated text.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6ab22d98426f44a291fc7f7af896b1a5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
