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 positions scaled by d3.scaleLinear and axes rendered using d3.axisBottom and d3.axisLeft. The code loads data via d3.csv, converts numeric fields, and draws the SVG chart with margins, axis labels, and a title. The visualization uses d3 v5 and renders entirely as SVG.
