{"version":"1.0","type":"rich","title":"Activity6 tutorial 4","description":"This bubble chart shows the relationship between average horsepower, torque, and highway miles-per-gallon for various car makes. Horsepower is plotted on the x-axis, torque on the y-axis, and the bubble’s radius encodes highway MPG, with a color scale distinguishing different manufacturers. The visualization uses D3.js v7 to render an SVG with animated tooltips that display the car make on hover. A legend explains the MPG bubble sizes, and a color-coded list identifies each make. The chart is built from the `bubblechart.csv` dataset, with axes labeled and a turbo color interpolation applied to the categorical color mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4c6d6356822e4b74a514375e0d9ea9e7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
