{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each bubble’s position encodes horsepower (x-axis) and torque (y-axis), while its size and color represent highway MPG and car make, respectively. Built with D3 v7, it uses `d3.scaleLinear` for axes and bubble radius, `d3.scaleOrdinal` for color encoding, and `d3.interpolateTurbo` for the palette. Hovering reveals a tooltip with the make name, and a legend explains bubble size values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2df3ec1fc92d4f1294ac6f677e4e1936?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
