{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s x-position maps to horsepower, its y-position to torque, and its size to highway MPG, while color encodes the make. Built with D3 v7, the chart uses `d3.scaleLinear` for axes and bubble radius, `d3.scaleOrdinal` with `interpolateTurbo` for color, and SVG circles with mouseover tooltips for details. A legend encodes both the MPG size scale and the categorical color mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/30ae0bd14a694ce7b40b74f29e070681?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
