{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"A bubble chart visualizes the correlation between average torque, horsepower, and highway MPG for 31 car makes, with each bubble colored by make and sized by MPG. Hovering reveals a tooltip displaying the make. The chart uses d3.csv to load data, d3.scaleLinear for axes and bubble size, d3.scaleOrdinal with d3.interpolateTurbo for colors, and d3.axisBottom/Left to render axes. SVG circles, a size legend, and a color legend are drawn, with mouseover, mousemove, and mouseleave events controlling the tooltip.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bfb09d2c95c9493bbedbbe2a8d6e21cc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
