{"version":"1.0","type":"rich","title":"Activity 6_ Task 4","description":"This bubble chart visualizes the correlation between average torque, average horsepower, and highway MPG across vehicle makes. Each circle represents a car brand, with its x-position mapped to horsepower, y-position mapped to torque, and the circle’s radius encoding highway MPG. A legend shows the mileage scale, while hover tooltips reveal the make. The chart uses D3 v7 with SVG elements, `scaleLinear`, and `scaleOrdinal` for color encoding. Data comes from a CSV file, and the visualization includes animated transitions during tooltip display.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f55c7f67a13d462d829d91780fc54a34?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
