Hovering reveals a tooltip displaying the make. The chart includes legends for bubble size and color categories, using SVG rendering with D3 v7 scales (d3.scaleLinear, d3.scaleOrdinal) and event handlers for interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd556de17e4e48fb94cc8926fef626ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
