{"version":"1.0","type":"rich","title":"Activity 6_Tutorial 4","description":"This example visualizes the correlation between average torque, horsepower, and highway MPG across multiple car makes using a bubble chart. Each circle represents a car make, positioned by horsepower on the x-axis and torque on the y-axis, with bubble size proportional to highway MPG and color encoding the make. The chart includes interactive tooltips, a legend for bubble sizes, and a color legend. It is built with D3 v7, using d3.csv for data loading, d3.scaleLinear for axes and sizing, and d3.scaleOrdinal for color mapping.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d84234dc1cf24a9ebc5b0ef0b3b53a57?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
