Cars Scatter Plot
This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository’s Auto MPG dataset. The visualization uses d3.scaleLinear for both axes, d3.axisBottom and d3.axisLeft with grid lines, and circles are appended to an SVG with a red, semi-transparent fill and a fixed radius of 10 pixels. Data is loaded from a CSV file using d3.csv, then parsed and rendered.
