{"version":"1.0","type":"rich","title":"Activity_7_Q2","description":"This visualization displays BMI distribution across age groups using a smooth area chart with interactive hover effects. The D3.js code loads CSV data, processes BMI values into High and Normal categories, and renders an SVG with gradient-filled areas. Users can hover to see a dashed line, circular marker, and tooltip showing age, BMI, and category. The implementation uses d3.area, d3.scaleLinear, d3.bisector, and d3.axisBottom/axisLeft for the chart structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b13ac7084eb744e495258d685031b479?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
