This scatter plot visualizes the relationship between horsepower and weight for a dataset of cars, sourced from the UCI Machine Learning Repository. Each car is represented as a semi-transparent red circle, with the x-axis showing horsepower and the y-axis showing weight. The visualization is built using D3 v5, employing `scaleLinear` for axis scaling, `axisBottom` and `axisLeft` for tick generation, and SVG rendering to draw the circles. The code also parses numeric fields from the CSV data to enable accurate plotting.
