This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Machine Learning Repository's Auto MPG dataset. Red semi-transparent circles represent individual cars, with axes labeled and a title displayed. The visualization is built with D3 v5, using `d3.csv` to load data, `d3.scaleLinear` for scales, and `d3.axisLeft` and `d3.axisBottom` for axes. Styling is applied via CSS to control circle opacity, tick appearance, and label fonts.
