Cars Scatter Plot
This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Auto MPG dataset. Each circle represents a car, positioned by its horsepower on the x-axis and weight on the y-axis, with grid lines and labeled axes for readability. Built with D3 v5, the code uses `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` to construct the scales and axes, while loading CSV data via the `csv` function. The SVG rendering applies a green, semi-transparent fill to the circles, with custom styling defined in CSS.
