{"version":"1.0","type":"rich","title":"act_6_4_task","description":"This visualization shows the correlation between average horsepower, torque, and highway MPG across car makes, with each bubble sized by MPG and colored by manufacturer. A tooltip appears on hover to display the make name. Built with D3 v7, it uses `d3.csv` to load data, `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` with `d3.interpolateTurbo` for colors, and `d3.axisBottom` and `d3.axisLeft` for axes. The SVG renders animated bubbles, a black tooltip, and a legend showing MPG values and color-coded makes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1a42893476ae4f4cb0d62feaf885854e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
