{"version":"1.0","type":"rich","title":"Activity6_Tutorial_4","description":"This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for various car makes, revealing that higher-performance vehicles tend to have lower fuel efficiency. Each circle represents a car manufacturer, with its x-position indicating horsepower, y-position indicating torque, and size scaled proportionally to highway MPG using `d3.scaleLinear`. The color of each bubble, assigned via `d3.scaleOrdinal` with `d3.interpolateTurbo`, distinguishes between makes. Hovering over a bubble triggers a tooltip displaying the make name. The chart includes a legend for bubble size values and uses the `d3` framework with SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/157081abc490483591e4e21302fda4b8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
