An interactive visualization of pathfinding around circular obstacles. It displays a set of draggable circles as obstacles and computes a path between two points, using A* search on a graph where nodes are tangent points on circle boundaries and edges are either "surfing" (straight line segments) or "hugging" (arcs along a circle's circumference). The graph includes bitangent lines between circle pairs. The Vue.js application renders the scene as an SVG, using custom vector math functions for geometric calculations and drag-and-drop interaction.

An interactive force-directed graph lets users create nodes by clicking, with new nodes automatically linking to any existing nodes within a 30-pixel radius. The visualization uses d3.layout.force for physics simulation, SVG circles for nodes, and lines for links, rendered in a React-free vanilla HTML page with d3.v3. A brown cursor circle tracks the mouse, and nodes are draggable via force.drag.

A force-directed dependency graph visualizes the relationships between Linux system components, with nodes colored by class and links styled by dependency type. The Vue component uses `d3.forceSimulation` with charge, collision, centering, and X/Y positioning forces to layout the SVG network, while zooming and panning are enabled via `d3.zoom`. Data is loaded from a JSON file listing nodes and typed links, rendered as circles and arrows with markers, supported by a grid pattern background.

A force-directed layout uses a d3.geom.quadtree for collision detection among 200 circles of varying radii, with a fixed root node at the center. The root’s position follows the mouse via an SVG mousemove event, causing the simulation to resume and repel other nodes. Circles are rendered as SVG elements with colors from d3.scale.category10, and d3.layout.force manages gravity and charge between nodes.

This example shows a force-directed layout of 200 colored circles that repel each other and collide as they move. Dragging the mouse moves a fixed root node, pulling the surrounding circles toward the cursor. The visualization uses D3 v3’s `d3.layout.force` with custom gravity and charge functions, and a quadtree via `d3.geom.quadtree` to efficiently handle collision detection between circles. Each circle’s radius is randomly assigned, and its fill color comes from a categorical scale (`d3.scale.category10`). The rendering is done in SVG, with positions updated on each tick event.

This visualization generates a dense packing of animated circles that grow from the center of an SVG canvas. Using a quadtree data structure to optimize collision detection, the algorithm iteratively places new circles in the largest available gaps, gradually increasing the number of candidate positions per circle. The code uses `d3.quadtree()` for spatial indexing and SVG `circle` elements with `transition()` animations to scale each circle's radius from zero. The process continues for 25,000 circles, with fill opacity randomly varied between 50% and 100%, creating an organically growing, space-filling composition.

This example shows a force-directed network graph with circular nodes and connecting lines, rendered as an SVG. The visualization loads JSON data from a GitHub gist, positions nodes using a physics simulation, and displays the resulting layout. The code uses d3.forceSimulation, d3.forceLink, d3.forceManyBody, and d3.forceCenter to compute node positions, then updates the SVG circle and line elements during each simulation step.

A cluster of 100 circles, each colored by one of four categories, moves under a force-directed layout in an animated SVG scene. D3's `d3.layout.force` continuously updates node positions, while a custom tick function applies directional offsets based on node index to separate groups into distinct clusters. Clicking or dragging any circle adds random jitter, causing the clusters to scatter and then re-form. The visualization uses D3 v3 with React, fading the entire SVG in over one second on load.

A force-directed layout uses D3's `d3.layout.force` to simulate repulsive and attractive forces among 200 circles, each with a random radius between 4 and 16 pixels. The root node is fixed at the center with a negative charge, pulling all other circles toward it while collision detection via `d3.geom.quadtree` keeps them from overlapping. As the simulation ticks, circle positions update in an SVG canvas, and users can drag the root node by moving the mouse, which resumes the force simulation to re-layout the surrounding nodes dynamically.
