{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This interactive bubble chart visualizes the relationship between horsepower, torque, and highway MPG for 31 car makes. Each circle is positioned by horsepower on the x-axis and torque on the y-axis, while its radius encodes highway MPG and its color represents the manufacturer. The chart uses d3.csv to load data and d3.scaleLinear for positioning and sizing. Hovering over a bubble triggers a tooltip displaying the make's exact specifications. A legend identifies each make, and axes are labeled with descriptive titles. The implementation uses d3.axisBottom, d3.axisLeft, and d3.schemeTableau10, rendering SVG circles with animated transitions via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ea3db5a91b0641579940ee0fd292456e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
