This scatter plot visualizes the relationship between horsepower and weight for a sample of cars from the UCI Auto MPG dataset. The code uses d3.scaleLinear, d3.axisBottom, and d3.axisLeft to construct the axes, and renders the data as red, semi-transparent SVG circles. The chart includes axis labels, a title, and a grid, with the data loaded via d3.csv and parsed into numeric fields before being passed to the render function.
