Practice D3 013121

D3 Example

This example demonstrates a basic force-directed network graph with three nodes and two links, rendered as SVG circles. The visualization uses `d3.forceSimulation` with `forceManyBody`, `forceLink`, and `forceCenter` forces to position the nodes, while a tick event updates each circle’s `cx` attribute based on the simulated x-coordinates. The code defines nodes and links as static arrays, with positions calculated entirely by the physics simulation. The example relies on D3 v6 and selects an SVG container by ID, but the script tag references a missing `bundle.js` file, so the simulation may not execute in practice.

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.

D3 Force Simulation

A force-directed network layout visualizes 100 nodes and 300 random links, rendered as circles and lines in an SVG canvas. The example uses D3 v4’s `d3.forceSimulation` with `forceCenter`, `forceManyBody`, `forceLink`, and `forceCollide` forces to compute positions. Nodes are draggable via `d3.drag`, which updates fixed positions (`fx`, `fy`) during interaction. The animation updates node coordinates and link endpoints on each simulation tick.

D3 Force Simulation

This example displays a static force-directed network of 100 circles and 100 randomly generated links on an SVG canvas, using D3 v4. Nodes are positioned randomly and rendered as steelblue circles, while links are implied but never drawn, so the visualization focuses solely on node placement. The code prepares data structures for a force simulation but does not call d3.forceSimulation, leaving the layout in its initial random state.

My First D3 Programming

This example demonstrates a force-directed network visualization, showing connected nodes arranged through simulated physical forces. The graph renders as SVG circles and lines, with node positions updated dynamically through the simulation. Using D3’s `d3.forceSimulation` and force link/collision/charge forces, the code reads data from a predefined array and updates the SVG elements on each tick. Styling comes from an external stylesheet, while the HTML serves as the container for the D3-managed visualization.

D3 Force Simulation

A force-directed network visualization shows 100 nodes and 300 random links in a 400-by-400 SVG canvas. The layout uses D3 v4’s `d3.forceSimulation` with `forceCenter`, `forceManyBody`, `forceLink`, and `forceCollide` to position and repel elements. Nodes render as steelblue circles, links as gray lines, and drag behavior lets users reposition nodes through `d3.drag`. The simulation updates node and link coordinates on every tick via the `ticked` function.

D3 Force

This example demonstrates a simple force-directed simulation of three nodes (Alice, Bob, and Carol) connected by two links, rendered as circles inside an SVG element. The visualization uses D3’s `forceSimulation` API with `forceManyBody`, `forceLink`, and `forceCenter` forces, which are explicitly set up to model charge, link, and centering effects. The simulation’s `on('tick')` handler logs a message to the console, but the positions are not yet updated or drawn, so the visualization’s visible output is minimal. The code references the D3 library loaded via a CDN and selects the SVG container using `d3.select`.

Fork of Canvas Force Tutorial

This example shows a force-directed network graph built from a CSV file of names and connection weights, rendered as circles and lines on an HTML5 Canvas. It uses d3.forceSimulation with forceX, forceY, forceCollide, forceManyBody, and forceLink to position the nodes, updating the canvas on each simulation tick via the `ctx` drawing context. The visualization reads data.csv asynchronously with d3.csv, constructs the node and link arrays, and then starts the simulation, with node radius fixed at 7 pixels.
