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.
