This scatter plot visualizes the relationship between vehicle weight and horsepower using data from the auto-mpg dataset. Each circle represents a car, plotted using `d3.scaleLinear` with `d3.extent` for domain scaling and `d3.axisBottom` and `d3.axisLeft` for axes. The chart includes gridlines via tick sizes and axis labels, with formatting applied through `d3.format`. Data is loaded as CSV and rendered as an SVG in React with D3 v5.
