This scatterplot visualizes the relationship between vehicle weight and horsepower using the classic cars dataset. Each circle represents a car, with the x-axis showing weight and the y-axis showing horsepower. The visualization uses D3 v5 within a React framework, rendering as SVG. It employs `d3.scaleLinear` for both axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.extent` to determine the data domains. The circles are semi-transparent steel blue, with grid lines provided by axis tick marks.
