This scatter plot visualizes the relationship between vehicle horsepower and weight using data from the UCI Machine Learning Repository's Auto MPG dataset. Red semi-transparent circles represent individual cars, plotted with D3.js scales and axes. The visualization uses `d3.scaleLinear` for both axes, `d3.extent` for domain calculation, and `d3.axisBottom` and `d3.axisLeft` for tick marks and labels. Data is loaded via `d3.csv` from a remote URL, with numeric fields converted using unary plus operators.
