{"version":"1.0","type":"rich","title":"Activity 7 Task 5","description":"This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position reflects horsepower on the x-axis and torque on the y-axis, while its radius encodes highway MPG, with color distinguishing car brands. Hovering reveals a tooltip showing the make. The visualization uses D3 v7’s `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.csv` to load data, with a legend for MPG values and a categorical color scale. SVG rendering and CSS transitions enhance interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/541d35fe00fa422e859153f92af122a7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
