This example shows a small directed graph with four nodes and two weighted links rendered as an SVG. Nodes are labeled with their names from a JSON file, and link stroke width encodes the weight value. The visualization uses the D3.js v2 force-directed layout API, `d3.layout.force`, to position nodes, with link coordinates updated on each simulation tick. Node dragging is enabled via the `force.drag` call.

A simple force-directed graph rendered in SVG shows four labeled nodes (H, I, J, K) connected by four links in a small network. The code uses the D3.js v3 `d3.layout.force` API with gravity, charge, and link distance settings to position the nodes dynamically, while circles and lines are styled via CSS classes. The simulation updates node and link coordinates on each tick event, with no interactivity beyond the native drag behavior attached through `force.drag`.

This example presents a small force-directed network graph with six nodes labeled A through F and six weighted links. Node color is a uniform olive, while link thickness reflects the numeric “value” assigned to each connection. The underlying data, loaded from a JSON file, includes additional attributes like gender and occupation for each node, though these are not visually encoded. The visualization uses d3.forceSimulation with link, charge, and center forces, and supports interactive dragging. Node positions are updated on each tick, with SVG circles and text labels rendered through D3’s data join.

This example visualizes a force-directed network graph, showing nodes labeled with names and connected by links of varying thickness, using an SVG rendering approach. The graph layout is computed with `d3.forceSimulation`, applying `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to position nodes and edges dynamically. Data is loaded from a JSON file containing edge and node definitions, with colors assigned via a `d3.scaleOrdinal` scheme. The nodes are draggable, and the simulation updates positions on each tick, with link thickness reflecting edge values.

This example shows a small directed force-directed network graph with six olive-colored nodes and four links of varying thickness, where each node is labeled with its ID. It uses `d3.forceSimulation` to layout the graph, with a `d3.forceLink` for edges, `d3.forceManyBody` for repulsion, and a center force to position nodes. Node positions update on each tick, and links are drawn as lines with stroke-width proportional to the square root of the link value. Drag handlers via `d3.drag` allow the user to reposition nodes. The graph data comes from a JSON file containing nodes A–F and six links; rendering is in SVG within a 500×500 viewport.

A force-directed network graph visualizes six nodes and five weighted links, with node size representing group membership and link thickness indicating connection strength. The graph uses D3 v4’s `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to position circles and lines in an SVG. Data loads asynchronously from a remote JSON file, and the `ticked` function updates node coordinates and link endpoints after each simulation iteration. The visualization renders as a simple, static SVG with no interaction.

This example visualizes a force-directed network graph using the d3.v4 library. The code loads node and link data from a JSON file and positions the nodes through `d3.forceSimulation`, applying repulsion (`d3.forceManyBody`), link constraints (`d3.forceLink`), and centering forces. Rendered as an SVG, nodes are orange circles with black strokes, connected by green lines. Node labels are positioned relative to each circle's computed coordinates, and the animation runs continuously as the force simulation updates the layout.

This example shows a force-directed graph of interconnected nodes, where each node is a small circular glyph and links are drawn as thin, slightly curved lines. The graph uses an offline dataset stored as an array and relies on `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to compute layout, while `d3.drag` enables user interaction. The visualization is rendered to a Canvas 2D context, with each frame clearing and redrawing positions from the simulation’s tick events. Node colors and sizes are static, and the code does not include labels or tooltips.

This example presents a force-directed graph layout of a synthetic network dataset, rendered as an interactive SVG. It uses the D3.js library’s `forceSimulation` API to compute node positions and `forceLink` for edge constraints, with nodes colored by a categorical attribute. The visualization includes draggable nodes and a simple tooltip on hover, while the underlying data is generated programmatically in the JavaScript file.
