This scatter plot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset. Each red circle represents a vehicle, with its position determined by d3.scaleLinear functions mapping the data to SVG coordinates. The visualization includes labeled axes with tick marks, a custom x-axis title, and gridlines created using d3.axisBottom and d3.axisLeft. The data is loaded via d3.csv and parsed to numeric values before rendering.
