DAND-documentation visualizes a network of file interactions, mapping how metadata and content connect across a repository. The visualization uses a force-directed layout via `d3.forceSimulation` to position nodes representing individual files, with links showing dependencies. Each node’s color and size encode the file type (e.g., `.txt` vs. `.rmd`) and its degree of connectivity, while hover effects reveal detailed tooltips via `d3.select` and `transition.attrTween`. The underlying data comes from a gist by Heronwang, parsed directly from the listed filenames, and the rendering leverages Canvas `getImageData` for pixel-level interaction feedback.

Gist f867f21cc0dbe672f0d10ab163876c38

This example shows a force-directed network visualization built with D3.js, rendering connections between GitHub repository nodes. It uses d3.forceSimulation with charge, link, and center forces to position the nodes, while links are drawn as SVG paths. The visualization reads repository and relationship data from a gist, with each node colored and labeled based on its source repository. Hovering highlights connected links and neighbor nodes, with a zoom and pan interface via d3.zoom for exploring the graph.

D3 force labels 01

This example visualizes a network of photograph-related metadata using a D3 v3 force-directed layout. Nodes are shown as GitHub favicon images, with yellow labels identifying each node by name, while yellow lines represent links between them. The graph includes nodes grouped by categories such as photographic works, collections, and photographers like James Anderson and Dorothea Lange. The code uses `d3.layout.force` to simulate the layout, applying gravity, distance, and charge parameters, and updates node and link positions on each tick event with SVG elements.

Gist f0e5d88500fd76302d5a1b9ad07b6ae1

This visualization shows a force-directed network graph of file dependencies, where each node represents a file and links connect related components. The layout uses d3.forceSimulation with custom collision and charge forces to position nodes, while link opacity encodes connection strength. The rendering relies on Canvas 2D drawing with getImageData for pixel-level hover detection. The data comes from a static list of file paths, including Microsoft.Mashup.OleDb.1 and Montego.OleDb.1, with edge weights derived from shared prefixes. The code also uses transition.attrTween to animate node positions smoothly when the layout stabilizes.

Gist 0bb5514393bdd878235e51ed2fdd3724

This example visualizes the relationships between file names and their associated directory paths using a force-directed graph layout. The code employs `d3.forceSimulation` to position nodes and `d3.forceLink` to draw connecting edges, with each node rendered as a colored circle. The graph is built from a parsed file tree structure, likely derived from object keys or an array of paths, and uses `d3.select` for DOM manipulation. Labels are attached to nodes via SVG text elements, while the simulation updates positions on each tick. The rendering relies on an SVG container, with node colors distinguishing file types from directory paths.

D3 Node-link Diagram With Force-directed Layout

This interactive D3 node-link diagram visualizes a force-directed network layout using data from the SOC-FIRM-HI-TECH repository. It shows the connections between nodes, with link thickness proportional to edge weight and node color assigned by ID via `d3.scaleOrdinal` and `d3.schemeCategory10`. The graph is rendered as an animated SVG using `d3.forceSimulation` with link, many-body charge, and center forces, allowing drag interactions. Hovering over a circle reveals a tooltip with the node ID, powered by D3 transitions and mouse events.

Gist 8a97689739c217f28474d80c89013628

This visualization uses a force-directed graph to show relationships between entities, with nodes positioned by `d3.forceSimulation` and links drawn as curved paths. The code computes node sizes and colors from quantitative attributes, while a canvas overlay via `d3.geoPath` and `getImageData` samples pixel density to modulate link opacity based on local clustering. It employs a custom `transition.attrTween` to animate node drift when the simulation restarts, and uses the `d3.hierarchy` API to flatten nested data from a JSON file. The visualization reads credentials from an `env.list` file for a private data source, but the rendering logic is independent of that authentication step.

Webdav URL

This example shows a force-directed network graph of files and folders stored in a WebDAV database, rendered as an interactive D3.js visualization. The graph uses `d3.forceSimulation` with custom link and charge forces to cluster nodes, while each node’s size reflects file size and color indicates file type. Data is fetched live from the WebDAV endpoint at `http://localhost:8080/exist/webdav/db/`, parsed from the directory listing, and then bound to circle elements. The code also employs `d3.drag` for node repositioning and `d3.zoom` for panning and scaling the canvas.

Gist bf027117c9b0bdfb633414ab5bd84877

This example visualizes a network of file and folder connections from a Gist repository, using a force-directed graph layout to reveal clustering and link patterns. The code employs D3.js’s `d3.forceSimulation` with `forceLink` and `forceManyBody` to position nodes, while SVG paths and circles render the edges and vertices. A drop-down menu lets users filter the displayed links by type, and the visualization includes a legend and hover tooltips. The underlying data is hardcoded as a JavaScript array of node and link objects, reflecting the structure of a GitHub Gist.
