This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository Auto MPG data set. Red semi-transparent circles represent individual vehicles, with axes labeled and grid lines drawn. The visualization uses d3.csv for data loading, d3.scaleLinear for scaling, d3.axisBottom and d3.axisLeft for tick marks, and renders via SVG. Axis labels and a title are appended as text elements with custom styling.
