This scatter plot visualizes the relationship between horsepower and miles per gallon (MPG) for cars from the Auto MPG dataset. The code uses D3 v5 with SVG rendering, employing `scaleLinear` for both axes, `axisLeft` and `axisBottom` for ticks, and circles to represent data points with a fixed radius. Axes are labeled with rotated text for the y-axis, and the chart includes gridlines via tick sizes.
