This example visualizes the relationship between vehicle weight and horsepower for cars from the 1970s, using a scatter plot with semi-transparent blue circles. The chart includes gridlines and labeled axes for both variables, with a title above the plot. The visualization is built with React and D3.js, using `d3.csv` to load the dataset and `d3.scaleLinear`, `d3.extent`, `d3.axisLeft`, and `d3.axisBottom` to construct the scales and axes. The SVG rendering is handled directly through D3 selections.
