The chart includes interactive tooltips that display the car make upon hover. Implemented with D3 v7 (`d3.select`, `d3.scaleLinear`, `d3.scaleOrdinal`, `d3.axisBottom`, `d3.axisLeft`), the SVG rendering uses color-coded bubbles and a custom legend for MPG values, with data loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/16c4e69ce95c4429b6e7c5a8a6667a86?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
