This example presents a reusable scatter plot built with D3.js v7 inside a React application, using the SVG rendering approach. It visualizes a car dataset, plotting engine size against fuel mileage, with each dot representing a vehicle. The chart leverages D3 scales and axes for positioning, and custom styling with hover effects. Based on index.html, the code parses a CSV file with d3.csv and constructs a scatter plot demonstrating the relationship between car engine capacity and efficiency.
