{"version":"1.0","type":"rich","title":"Activity8_Task4","description":"This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG across different car makes. Each circle’s position encodes horsepower and torque on the x- and y-axes, while its radius and color represent highway MPG and manufacturer, respectively. The visualization uses D3.js (v7) with SVG rendering and includes interactive tooltips on hover, along with a legend showing MPG scale and color-coded makes. Data is loaded from a CSV file, and the chart animates transitions when the tooltip appears or moves.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1e3ae053eae84af7838936416dc00370?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
