This scatter plot shows the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG data set. Each circle represents a car, with position mapped by scaled linear axes. The visualization is built with D3 v5, using `scaleLinear` for both axes, `axisLeft` and `axisBottom` for ticks, and SVG circles for data points. Grid lines are drawn via axis tick sizing, and axis labels and title are added as SVG text elements.
