This example demonstrates a React-based interactive visualization that renders a dynamic particle system using HTML5 Canvas. The code leverages D3’s force simulation (`d3.forceSimulation`) to compute physics-based movement for multiple circular nodes, which are drawn each animation frame via the Canvas API. Each node’s position is updated continuously based on velocity and collision forces, creating a fluid, organic motion effect. The visualization is built with pure JavaScript and styled minimally through CSS, showcasing how React integrates with D3 and Canvas for real-time graphics without external charting libraries.
