This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG dataset. Each red, semi-transparent circle represents a car, with axes labeled accordingly. The visualization is built with D3 v5, using `d3.csv`, `scaleLinear`, `axisBottom`, and `axisLeft` to load data, scale positions, and render axes as SVG elements. The code explicitly parses all numeric fields, including mpg, cylinders, and acceleration, before plotting.
