{"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 circle’s x-position maps to horsepower, y-position to torque, and radius to highway MPG, while color distinguishes manufacturers. Built with D3 v7, the SVG rendering includes hover tooltips showing the make, a bubble-size legend for MPG values, and a color legend for all makes. Data is loaded from a CSV file, with scales created using d3.scaleLinear and d3.scaleOrdinal, and interactivity handled via mouseover, mousemove, and mouseleave events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/93eca0d1b2644936b776bbf7dc1a7e42?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
