This scatter plot visualizes the relationship between horsepower and weight for cars from the UCI Auto MPG dataset. The code uses D3.js v5 to load CSV data, apply linear scales with `scaleLinear`, and render SVG circles with red, semi-transparent fills. It constructs axes with `axisBottom` and `axisLeft`, including grid lines and custom positioning for labels like "Horsepower" and "Weight." The layout applies explicit margins and a title above the chart.
