This scatter plot compares car horsepower to weight using data from the auto-mpg CSV dataset. The visualization renders circles with opacity to show the relationship between the two variables, with axes labeled and a title displayed. The code uses d3.csv for data loading, d3.scaleLinear for scaling, and d3.axisBottom and d3.axisLeft for axis generation. SVG rendering is employed, with margins and tick sizes configured to create a clear, readable chart.
