Cars Scatter Plot
This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Auto MPG dataset. Red, semi-transparent circles represent individual car models, plotted using D3 v5’s `scaleLinear` for both axes. The SVG rendering uses `axisLeft` and `axisBottom` to create labeled axes, with grid lines and a title. Data is loaded as CSV and parsed into numeric fields before mapping to coordinates.
