{"version":"1.0","type":"rich","title":"Task8_Tutorial4","description":"This visualization shows the correlation between a vehicle's average horsepower, torque, and highway MPG, with each circle representing a car make. The chart uses position to encode horsepower on the x-axis and torque on the y-axis, while the radius and color of each circle represent the vehicle’s highway fuel efficiency and the manufacturer, respectively. Built with D3.js (v7) and rendered as an SVG, it uses `d3.scaleLinear` for axes and bubble size, and `d3.scaleOrdinal` with `d3.interpolateTurbo` for color mapping. Hovering reveals a tooltip with the car make, and the legend displays both the bubble size scale and a color key for all makes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ac5abfd3fbf14c0684a2ba18530e6ece?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
