{"version":"1.0","type":"rich","title":"Activity6_Task4 ","description":"This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG across different car makes. Each bubble’s x-position encodes horsepower, the y-position encodes torque, and the circle’s radius encodes highway MPG, while color distinguishes the car manufacturer. Hovering over a bubble reveals a tooltip with the make name. The chart, rendered as SVG, includes a legend for MPG and color-coded makes. Built with D3 v7, it uses `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.interpolateTurbo` for color mapping, with data loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c45b39f593074f61abbcf7c319a901fa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
