This scatter plot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset. Red, semi-transparent circles represent individual vehicles, with axes labeled accordingly. The visualization uses d3.csv to load data, d3.scaleLinear for both scales, and d3.axisBottom and d3.axisLeft with gridlines to render the chart. SVG circles are positioned using the scaled values, with text elements styled via CSS for the title and axis labels.
