{"version":"1.0","type":"rich","title":"Tutorial 4","description":"This tutorial shows the relationship between horsepower, torque, and highway MPG across 30 car makes, with car brand labels placed on a scatterplot. Each point’s position encodes horsepower and torque, while its size reflects highway MPG. The visualization uses D3.js with `d3.forceSimulation` to position labels and avoid overlaps, and `d3.scaleLinear` and `d3.axisBottom` to map and render axes. The data comes from the provided `bubblechart.csv` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6ef813b3ab5b4a4da6784bfa66f3f99b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
