{"version":"1.0","type":"rich","title":"Activity6_Task4","description":"This bubble chart visualizes the correlation between average horsepower (x-axis), average torque (y-axis), and highway MPG (bubble size) across various car makes. Each circle represents a car brand, with its position determined by the horsepower and torque values, while the bubble radius encodes highway fuel efficiency. Hovering over a circle reveals a tooltip displaying the car make. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble sizing, and `d3.interpolateTurbo` to assign colors to different makes. The chart includes a legend for bubble sizes and color-coded car makes, rendered as an SVG with interactive tooltips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8acccbf033a34737a2029d0aadbe3c22?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
