This scatterplot displays the relationship between horsepower and weight for cars in the Auto MPG dataset from the UCI Machine Learning Repository. Red, semi-transparent circles represent individual cars, with each point positioned using d3.scaleLinear for both axes. The chart includes labeled axes and a title, rendered as SVG elements. The code uses d3.csv to load data, converts numeric fields, and appends circles via data binding with d3-selection’s enter method.
