{"version":"1.0","type":"rich","title":"Activity6_Tutorial_4","description":"This D3.js bubble chart visualizes the correlation between average horsepower (x-axis), average torque (y-axis), and highway MPG (bubble size and color) for various car makes. The chart uses an SVG renderer with a tooltip that displays the car make on hover. The code relies on D3's scale functions (`d3.scaleLinear`, `d3.scaleOrdinal`) and the `d3.interpolateTurbo` color scheme. A legend maps bubble size to MPG values, and a categorical color legend identifies each car make. Data is loaded from a CSV file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fb0e1d556c904a25a7a5f21506e9e20f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
