{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This scatterplot visualization shows the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each bubble represents a car brand, with its x-position indicating horsepower, y-position indicating torque, and bubble size scaled to highway MPG. The chart includes a color-coded legend for car makes and an interactive tooltip displaying the make on hover. Using D3 v7's `d3.scaleLinear` and `d3.scaleOrdinal` with `d3.interpolateTurbo`, the visualization renders as SVG with smooth hover transitions and mouse event handlers for tooltip positioning.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e86b5dfc677a4084920b01c3284738d7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
