This scatter plot visualizes the relationship between horsepower and weight for a sample of cars, sourced from the UCI Machine Learning Repository's Auto MPG dataset. The visualization uses D3.js v5 to render an SVG graphic with scaled axes and semi-transparent red circles. The code leverages D3 APIs including `scaleLinear`, `axisBottom`, `axisLeft`, and `extent` to construct the chart. Axes are labeled, and axis lines are removed from the grid, which uses tick marks and labels to display the data distribution.
