{"version":"1.0","type":"rich","title":"q_6","description":"A bubble chart compares car brands by horsepower (y-axis), torque (x-axis), and highway MPG (bubble size and color), with a legend mapping both bubble radius and ordinal color categories. Rendered as SVG with animation via D3 v7, it uses `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.interpolateTurbo` to encode continuous and categorical variables. Interactive tooltips display each brand's make on hover. Data comes from the bundled `bubblechart.csv` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/139d87886f844470a5863b6af8c96ef1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
