A small force-directed simulation places three colored circles, representing nodes, in a 500-by-500 SVG canvas. The code uses `d3.forceSimulation` with `d3.forceManyBody`, `d3.forceX`, and `d3.forceY` to animate node positions, while a `tick` handler updates the circles' `cx` and `cy` attributes. The simulation restarts at timed intervals, first removing a node from the data array, then re-adding it, and finally pushing a new node, demonstrating how the layout adjusts to dynamic data changes.

This example visualizes a network of interconnected nodes, likely representing user connections or data relationships, using a force-directed layout. The visualization employs D3’s `d3.forceSimulation` to compute the physics of node positions and link forces, while `d3.select` and SVG elements handle rendering. The scene is drawn against a dark background, with nodes as circles and links as lines, suggesting a real-time or interactive graph. The code also integrates a canvas-based `getImageData` operation, possibly for pixel-level effects or hit detection, though the primary display relies on SVG. Data appears to originate from a static gist, emphasizing structure over live data feeds.

D3 Force Simulation

A network of 100 circles and 300 random links forms a force-directed layout rendered as SVG. The example uses d3.forceSimulation with center, charge, collide, and link forces to position nodes dynamically. Each circle is a node, and lines represent links, with node age assigned randomly but not visually encoded. The simulation updates positions on each tick, and drag behavior is referenced from Mike Bostock’s block, though not implemented here. Node and link data are generated randomly, and the viewport is fixed at 800 by 400 pixels.

D3 Force Simulation

This example shows a force-directed layout with 100 randomly connected nodes rendered as steelblue circles on an SVG canvas. The code creates nodes and links with random positions and connections using `d3.range` and `Math.random`. It uses `d3.select` to bind data and append circle elements with `attr` calls for positioning and styling. However, the simulation itself is not implemented—no `d3.forceSimulation` is invoked, so the graph remains static rather than animated. The visualization relies on D3 v4 and renders entirely via SVG.

D3 Force Simulation

This example shows a force-directed network layout of 100 nodes and 300 randomly generated links, rendered as circles and lines in an SVG canvas. The visualization uses `d3.forceSimulation` with three forces: `d3.forceCenter` to pull nodes toward the middle, `d3.forceManyBody` with negative strength for repulsion, and `d3.forceLink` to maintain a 50-pixel link distance. The simulation runs continuously via a `tick` event, updating node positions and link coordinates each frame. Nodes are interactive through `d3.drag()`, allowing users to manually reposition them while the simulation responds.

D3 Force Simulation

This example displays a static force-directed layout of 100 randomly positioned circles rendered as an SVG network. It creates nodes with randomized x and y coordinates using `d3.range` and `Math.random`, then appends them as circle elements to a 400 by 400 SVG canvas. Although the code sets up node data, it does not call `d3.forceSimulation` or create any links, so the circles remain in their initial random positions without movement. The visualization uses D3 v4 and directly manipulates SVG circle attributes.

This example uses D3.js (v5) to visualize a network of chemical compounds, targets, and annotations as linked circles. It shows how nodes are arranged in three concentric rings based on their group—compounds on the outer ring, targets on the middle, and annotations at the center—using `d3.forceSimulation` with a custom `forceRadial` constraint. Links between nodes are rendered as black lines, with stroke width and class names indicating link type. The code loads `nodes.csv` and `links.csv`, then applies forces for collision, link distance, and radial positioning. The resulting static SVG chart is built entirely through D3’s data-join and tick event updates.

D3 Force Simulation

A force-directed network of 100 nodes and 300 randomly generated links settles into a stable layout under a centering force, many-body repulsion, link distance constraints, and collision avoidance. The visualization uses D3 v4's `d3.forceSimulation` with `d3.forceCenter`, `d3.forceManyBody`, `d3.forceLink`, and `d3.forceCollide` to animate the physics, while nodes are draggable via D3's drag interaction. The simulation updates an SVG canvas on each tick, redrawing lines and circles as positions change. The random data is generated programmatically, creating an abstract, interactive demonstration of force-based layout.

Force Graph Starter

This example shows a minimal force-directed graph with three nodes and two links, rendered as SVG circles and lines. The simulation uses `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` to position the nodes, while a `tick` event updates the circle and line coordinates. Data consists of hardcoded node IDs and link indices in `index.js`, styled with a large font size and hidden overflow via `index.css`. The code imports from D3 v6 and runs within a React-free HTML page, using a fixed 960×500 SVG viewport.
