{"version":"1.0","type":"rich","title":"Activity_6_Task_4","description":"This interactive bubble chart shows the correlation between average horsepower, torque, and highway MPG across 31 car makes, with bubble size encoding MPG and color distinguishing each brand. Hovering reveals a tooltip with the make name. Rendered in SVG with D3 v7, it uses `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` with `d3.interpolateTurbo` for colors, and mouse event handlers for tooltip interaction. Data comes from the included `bubblechart.csv`, with a legend for MPG values and make labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/995d6bf4416d41b699e48bfdad591ba7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
