{"version":"1.0","type":"rich","title":"Activty6_Task_4","description":"This bubble chart shows the correlation between average horsepower, torque, and highway MPG across multiple car makes. Each circle’s position encodes horsepower (x-axis) and torque (y-axis), while its radius and color represent highway MPG and car make, respectively. Built with D3 v7, the visualization uses `d3.csv` to load data, `d3.scaleLinear` and `d3.scaleOrdinal` for encoding, and interactive tooltips with mouseover events. Circle size and color are mapped via legends, and rendering uses SVG with hover animations for emphasis.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bcdd6029e38f46f4ae0cfc6eb991d0ee?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
