{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This bubble chart visualizes the correlation between average horsepower (x-axis), torque (y-axis), and highway MPG (bubble size and color) for 31 car makes. Each car brand is represented by a colored circle, with turbo color interpolation mapping distinct hues to each make. The D3.js v7 code loads CSV data, uses `d3.scaleLinear` for axes and bubble radius, and `d3.scaleOrdinal` for color assignment. Interactive tooltips reveal the car make on hover, while a legend displays MPG value scaling. The visualization is rendered as an SVG with smooth opacity transitions on mouse interactions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d9e82360b6d4f779f15ad97216692b3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
