{"version":"1.0","type":"rich","title":"Question4-Bubble chart","description":"This bubble chart visualizes the correlation between average horsepower (x-axis), average torque (y-axis), and highway MPG (bubble size) for 15 car manufacturers. Each bubble is colored by manufacturer using `d3.scaleOrdinal` with an interpolated turbo color scheme. The visualization includes an interactive tooltip that displays the manufacturer name on mouseover, implemented with D3 event handlers. A legend shows representative bubble sizes for 20 and 40 MPG values, alongside a color-coded manufacturer key. The chart is rendered as SVG with `d3.axisBottom` and `d3.axisLeft` for axes, and uses `d3.csv` to load the dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5682a9e3d99f49d0acb2b65a6112f5aa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
