This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository's Auto MPG dataset. Red, semi-transparent circles represent each car, with the plot showing a clear positive correlation between the two variables. Built with D3.js v5, the visualization uses `scaleLinear`, `extent`, `axisBottom`, and `axisLeft` to construct the axes, while loading data via the `csv` function. The SVG rendering includes axis labels, grid lines, and a title, with styling applied through an external CSS file.
