This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Auto MPG dataset, rendered as red semi-transparent circles on an SVG canvas. Using D3 v5, the code employs `scaleLinear` for both axes, `axisLeft` and `axisBottom` for gridlines and ticks, and `extent` to compute domains. The data is loaded via `csv` from a remote URL, parsed to numeric values, and then plotted with circle elements.
