Forked from React & D3 Starter

This interactive particle constellation visualizes 100+ colored particles that move with physics-based velocity, bounce off screen edges, and connect to nearby particles with fading lines. Particles are attracted to the mouse cursor, growing larger when approached. Built with React 19 and D3.js v7, the example uses d3.interpolateRainbow for gradient colors and requestAnimationFrame for smooth 60fps animation. Live sliders adjust particle count and connection distance, while a "Regenerate" button randomizes positions and colors through React state management.

AI-generated description

Particle Constellation ✨

An interactive particle system built with React and D3.js featuring:

  • 100+ animated particles with physics-based movement
  • Dynamic connections between nearby particles
  • Mouse interaction - particles are attracted to your cursor
  • Real-time controls to adjust particle count and connection distance
  • Beautiful gradient colors using D3's color interpolation

Features

  • Smooth 60fps animations
  • Particles bounce off screen edges
  • Connections fade based on distance
  • Particles grow when near the mouse cursor
  • Customizable parameters with live sliders

How to Use

  1. Move your mouse around to attract particles
  2. Adjust the particle count (20-200)
  3. Change the connection distance to see different patterns
  4. Click "Regenerate" for new random colors and positions

Built with React 19 and D3.js v7 🚀

Fork of React Starter

This fork of a React starter demonstrates a real-time, interactive particle system rendered on an HTML canvas. It uses `d3.forceSimulation` to manage particle physics, with forces like charge and collision driving movement across the viewport. The `useRef` and `useEffect` React hooks manage the animation loop, continuously updating the canvas via `requestAnimationFrame`. The display shows a dense cluster of small circles that slowly dissipates and re-forms based on the configured force parameters, providing a live example of force-directed layout in a React component.

This example renders a real-time, animated visualization of a particle system using React and the D3.js library. It leverages `d3.forceSimulation` to compute physics-based movement for a set of nodes, which are rendered as circles on an SVG canvas. The simulation applies forces such as charge and collision detection to create dynamic, organic clustering and dispersion. Data is generated procedurally within the component, with each particle's position and velocity updated on every animation frame, producing a continuously evolving visual pattern. The code integrates React's state management to trigger re-renders as the simulation state changes.

Fork of React & D3 Starter

A force-directed network diagram maps interconnected nodes and edges, using positioned circles and lines to reveal cluster structure. The visualization is built with React 19 and D3, where `d3.forceSimulation` computes layout physics, while `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` define attraction, repulsion, and centering forces. Node and link elements are rendered as SVG circles and lines, with drag behavior enabled via D3’s `drag()` handler to let users rearrange the graph interactively.

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.

Fork of React & D3 Vibecoding Starter

This interactive galaxy visualization displays 2,000 stars arranged in a spiral pattern with a glowing center, representing stellar temperatures through color (white/blue for hot, orange for cool). Stars twinkle automatically, and hovering brightens them while clicking triggers an explosion animation. The code uses React with D3 v7's `scaleLinear` and `randomNormal` functions to position stars, while SVG filters with `feGaussianBlur` create the glow effect on the galactic center and spiral arms.

Fork of React & D3 Starter

This example demonstrates a force-directed network visualization built with React and D3, showing nodes connected by edges that repel and attract through physical simulation. The code uses `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to compute node positions, while React handles rendering of SVG circles and lines. Interactive drag behavior is implemented via D3’s `drag` event handlers, updating the simulation’s alpha target on each interaction. The visualization renders from static, hardcoded data in the source files, with no external dataset or dynamic loading.

Fork of React Starter

An interactive circular heatmap visualizes daily birth counts for 2024, with colored dots orbiting a pulsing center circle. The visualization uses a D3.js v7 SVG animation to map birth data from a CSV file, encoding values through color gradients and glow effects. Hovering over data points reveals details via React state management, while CSS transitions and D3's ease functions create smooth orbital movement.
