This scatter plot visualizes the relationship between horsepower and weight for cars from the auto-mpg dataset. Each semi-transparent steelblue circle represents a car, with positions determined by linear scales mapping the data attributes to SVG coordinates. The chart includes labeled axes with gridlines and a title, using d3.csv for data loading, d3.scaleLinear, d3.axisLeft, and d3.axisBottom for scales and axes, all rendered as SVG elements.
