{"version":"1.0","type":"rich","title":"Activity 6_Task 4_Tutorial","description":"This visualization is an animated bubble chart that explores the relationship between average horsepower, torque, and highway MPG across different car makes. Each circle represents a car brand, with its horizontal position mapping to horsepower, vertical position to torque, and size encoding highway MPG. Color further distinguishes the makes. The chart uses D3.js v7 with the `d3.scaleLinear` and `d3.scaleOrdinal` APIs, rendered as an SVG. Interactive tooltips, implemented via `d3.select`, appear on mouseover. A legend uses sized circles to communicate the MPG scale.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/21e58a3af59646cdaf1f258d1a6c46ee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
