{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"A bubble chart displays the correlation between average horsepower, torque, and highway MPG for various car makes, with each bubble’s position determined by horsepower (x-axis) and torque (y-axis), while its size and color represent MPG and brand, respectively. The visualization uses D3.v7’s `scaleLinear` for axes and bubble radius, `scaleOrdinal` with `interpolateTurbo` for color mapping, and `axisBottom`/`axisLeft` for tick marks. Interactive tooltips appear on hover, and a legend indicates MPG values. Data comes from `bubblechart.csv`, rendered as SVG with animated transitions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cff1dd2dee834eb1b2735bd4e17ecb06?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
