Each circle's position encodes horsepower on the x-axis and torque on the y-axis, while its size and color represent highway MPG and car make respectively. The visualization uses D3 v7 to load CSV data, create SVG scales and axes, and render interactive bubbles with mouseover tooltips. A legend explains the bubble size scale, and hover effects highlight individual data points.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ab48138660b441ac9bfa73700c42ae55?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
