This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG dataset. Each red semi-transparent circle represents a car, with position determined by its horsepower on the x-axis and weight on the y-axis. The visualization uses D3 v5 to load CSV data, scale linearly with `scaleLinear`, and render axes via `axisBottom` and `axisLeft`. Titles and axis labels are added as SVG text elements, with styling applied through an external CSS file.
