{"version":"1.0","type":"rich","title":"task4","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position reflects horsepower and torque on the x- and y-axes, while its radius and color encode highway MPG. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` with `interpolateTurbo` for color, and SVG for rendering. Interactive tooltips appear on mouseover, and a legend explains the MPG-to-size mapping. Data comes from the provided `bubblechart.csv` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/13b12d1bc121451f99e5e49d5be823d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
