This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Auto MPG dataset. Red semi-transparent circles represent individual vehicles, revealing a positive correlation between the two attributes. The code uses d3.csv to load data, d3.scaleLinear for both axes, and d3.axisBottom/axisLeft to render ticks with gridlines. SVG rendering displays the title, axis labels, and plotted points with fixed opacity.
