{"version":"1.0","type":"rich","title":"Question 4","description":"A bubble chart visualizes the correlation between engine displacement, acceleration, and highway MPG for 1970s automobiles. Each circle represents a car model, positioned by its displacement and acceleration values, with the circle's radius scaled according to its MPG rating. The chart employs color encoding per car manufacturer, using the `d3.interpolateTurbo` color scale. Hovering over a bubble reveals a detailed tooltip displaying the car's make. Data is loaded from a local CSV file using `d3.csv`. The visualization includes a legend for both MPG values and manufacturer colors.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c220632dbd048479430da40cd69f49f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
