{"version":"1.0","type":"rich","title":"Question4_Bubble chart","description":"This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for various car makes. Each circle’s position encodes horsepower and torque on the x and y axes, its size reflects highway MPG, and its color distinguishes the car brand. Built with D3 v7, the chart uses `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` for color mapping, and interactive tooltips on mouseover. Data is loaded from a CSV file, and the visualization is rendered as an SVG with a legend for MPG values and brand colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5e69e30b43e749218b33981d282577ca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
