{"version":"1.0","type":"rich","title":"Activity-7Q2","description":"Three overlapping area layers compare horsepower, torque, and highway MPG across car brands on a shared point scale, with distinct steelblue, orange, and green fills and a matching legend. The chart renders to SVG using D3 v6, loading CSV data remotely and parsing numeric fields. It employs `d3.area` generators, `scalePoint` and `scaleLinear`, `axisBottom` with rotated labels, and `axisLeft`, while tooltips appear via appended `title` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/627d50d2cf8d48ada4b32995a4766cbd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
