Cars Scatter Plot
This scatter plot visualizes the relationship between horsepower and weight for 392 cars from the UCI Machine Learning Repository’s Auto MPG dataset. Red circles mark each vehicle, with axes labeled and a title displayed. The code uses D3 v5’s `csv`, `scaleLinear`, `axisLeft`, and `axisBottom` to load data, map values, and render SVG axes. Tick marks extend across the chart, while circle opacity is set in CSS for readability.
