This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Auto MPG dataset. The code uses D3 v5 to load CSV data, create linear scales for both axes, and render red, semi-transparent circles for each car. The chart includes labeled axes and a title, with gridlines and tick marks styled via CSS. The visualization demonstrates a straightforward data exploration using D3's `scaleLinear`, `axisBottom`, `axisLeft`, and SVG rendering.
