A dense cluster of a thousand particles circulates within a circular boundary, with their motion shaped by a D3 force simulation that balances collision, velocity decay, and a speed-limiting force. Clicking introduces a central vertical barrier that temporarily divides the system, altering particle trajectories and energy distribution. The simulation runs on a Canvas, with real-time red and green line charts at the bottom tracking the average squared velocities of particles on each side of the divider. The code uses `d3.forceSimulation`, custom force functions, `d3.scaleLinear`, and Canvas 2D rendering.

AI-generated description

Trying to make sense of the energy parameters of a simple simulation. forceCollide tends to inject energy into the system, while velocityDecay() removes some.

So, when the density of dots is low, energy tends to decrease; if it's high, energy diverges. We add another force that speeds up slow particles and slows down the fastest…

Click to add a central barrier.

Vortex Emergence

A simulation of 4,000 particles in a divided container shows energy dynamics: the left side maintains a swirling vortex, while the right side disperses into chaotic motion. A barrier with a gap controls particle flow between halves. The visualization tracks and plots mean squared velocities for each side as red and green line charts below. Built with D3 v4, it uses `d3.forceSimulation` with custom forces for collision, bouncing, and speed limits, rendering particles on Canvas and the energy charts as SVG paths.

Not an Ideal Gas

A simulation of 800 particles in a box with a central gap shows how the mean squared velocity evolves over time, plotted as a line chart below. The gap’s aperture shrinks as the simulation cools, and clicking the canvas restarts the process. The code uses `d3.forceSimulation` with a custom `forceCollide` and `velocityDecay`, plus custom bounce and barrier forces. Rendering combines Canvas for the particles and a d3 `area` path on SVG for the speed trace.

Untitled

This example visualizes a dynamic, two-dimensional particle system where thousands of glowing points drift and collide within a bounded rectangular field. It shows the emergent patterns of clustering and dispersion as forces of attraction and repulsion act on the particles over time. The code uses `d3.forceSimulation` with custom force functions to manage particle velocities and positions, rendering each frame to an HTML5 Canvas. Particle trails are created by semi-transparent redraws, and the interaction of the forces produces a fluid, organic motion across the display.

Expand and fill force (work in progress)

Five hundred colored circles cluster in a cloud, then slowly diffuse outward as a force simulation seeks lower-density regions. The visualization uses custom forces within d3.forceSimulation, including a grid force and a hexbin-based expand force that samples random hexagon rotations and pushes nodes toward emptier neighboring bins. Rendered on Canvas, the circles respond to mouse movement, with the first node pinned to the cursor and the simulation restarting on interaction. The code employs d3.hexbin to compute density weights and d3.forceCollide to prevent overlaps.

Particle collision

A swarm of 1,500 glowing particles falls and collides within shifting circular walls and a planet-like boundary, leaving colorful motion trails on a black canvas. The simulation uses `d3.forceSimulation` with custom collision, gravity, and wall-locking forces, rendered via Canvas 2D. Two particle groups cycle through D3 color interpolators (e.g., `d3.interpolateViridis`, `d3.interpolateMagma`), and randomized settings for radius, gravity, and palette timing make each reload unique.

Brownian Motion Constrained in Rectangle

A canvas displays 200 particles performing Brownian motion inside a rectangle, bouncing elastically off its boundaries. The simulation uses d3.forceSimulation with custom forces for random motion and container collision, plus d3.forceCollide to prevent overlaps. A Voronoi diagram, computed with d3.voronoi, generates an Urquhart graph—its edges are drawn as thick gray lines beneath thin black ones, with white-stroked yellow dots marking each particle. Clicking drags the first node, restarting the simulation.

Déménagement 1

Eight thousand points drift outward from the center of a canvas, then pause and leap in random directions, leaving a faint ring before settling into a second, radial distribution. The simulation uses `d3.forceSimulation` with a custom force that randomly repositions particles via `d3.randomLogNormal`, while a separate rendering loop draws the points as black and grey circles. A circular reference path is stroked to indicate the target radius, and the logarithmic scale maps coordinates to screen positions.

Collision Detection

A thousand circles of random radii are arranged into a tidy cluster, with d3.forceCollide preventing any overlap between them while d3.forceX and d3.forceY gently pull the whole group toward the center. The simulation runs on a fixed 960×960 canvas, where each tick clears the drawing and renders all circles as filled and stroked arcs. The code uses d3.forceSimulation with a velocity decay of 0.2, and draws the result directly via the Canvas 2D API.
