{"version":"1.0","type":"rich","title":"Task4 ","description":"This bubble chart visualizes the correlation between average torque, horsepower, and highway MPG across 31 car makes, using engine specifications from a CSV dataset. Bubble position encodes horsepower (x-axis) and torque (y-axis), while bubble radius represents highway MPG and color distinguishes car makes. The visualization includes interactive tooltips that display each make's name on mouseover, plus a legend showing MPG values and color categories. Built with D3 v7, it uses SVG rendering and employs d3.scaleOrdinal, d3.interpolateTurbo, and event handlers for the interactive features.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0cfa9d0bad704057988fb911c034e147?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
