A force-directed network diagram visualizes the structural graph of the HB/can_161 sparse matrix from the University of Florida Sparse Matrix Collection. The D3.js v3 code uses `d3.layout.force` to simulate node physics and renders circles and lines as SVG elements. Data is parsed from Matrix Market format by filtering comment lines and constructing node and link objects. The layout responds to drag interactions via `force.drag`, updating node positions and link coordinates on each tick.

AI-generated description

The University of Florida Sparse Matrix Collection provides a vast collection of interesting graphs in Matrix Market format. This example shows how to adapt this format to D3's force layout.

Matrix

A force-directed node-link diagram and adjacency matrix display the same network data, linked by interactive selection. Clicking a node highlights its corresponding row and column in the matrix. The code uses `d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` from d3-force for the layout, and `d3.select`, `d3.zoom`, and `d3.drag` for interaction. Nodes are sized by group, and the matrix uses precomputed edge hashes to determine cell connections.

Force Directed Graph

This example pairs an interactive force-directed node-link diagram with an adjacency matrix, showing the same network data in two complementary views. Users can drag nodes in the graph to reposition them, click a node to highlight corresponding row/column links, or click matrix cells to highlight edges. The force layout uses `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter`, while the matrix is rendered as SVG rectangles. Both views are synchronised via click events, with zoom support provided by a custom `d3.zoom` handler.

Force Directed Graph

A force-directed graph of 410 connected nodes is shown alongside an adjacency matrix, letting users explore network structure through either view. Clicking a node in the graph highlights its row and column in the matrix, while clicking a matrix cell highlights the corresponding link. The layout uses d3.forceSimulation with forceLink and forceManyBody, rendered as SVG circles and lines, with a zoom transform applied to both. The adjacency matrix is built from the same edge data, and hover effects use dynamically updated stroke colors and widths.

Matrix

This example combines a force-directed node-link diagram with an adjacency matrix visualization of the same dataset. Clicking a node in the force diagram highlights its corresponding row and column in the matrix, while clicking a matrix cell identifies a specific connection. The code uses `d3.forceSimulation`, `forceLink`, and `forceManyBody` for the graph layout, and renders both views as SVG with `d3.drag` for interaction and `d3.zoom` for panning and scaling.

Force Directed Graph

This example presents a node-link force-directed graph alongside an adjacency matrix, allowing comparison between the two visual representations. The graph uses d3.forceSimulation, d3.forceLink, and d3.forceManyBody to position nodes and links, while the matrix renders weighted connections as SVG rectangles. Clicking a node or matrix cell highlights corresponding rows, columns, and links in red, with the graph supporting drag-and-drop and zooming via d3.drag and d3.zoom.

Matrix

This example presents two coordinated views of the same graph data: a force-directed node-link diagram rendered with d3.forceSimulation, and an adjacency matrix using reorder.js for layout. Clicking a node in the network highlights the corresponding row and column in the matrix, while clicking a matrix cell highlights its associated link. The matrix uses SVG rectangles with fill-opacity representing connection strength, and both views support zooming and dragging. The code imports d3 v6, d3-force, and reorder.js libraries.

Force Directed Graph

A force-directed graph and adjacency matrix display network data side-by-side. The graph shows nodes as colored circles connected by links, while the matrix uses cells with opacity representing edge weights. Clicking a node or matrix cell highlights the corresponding row and column in both views. The visualization uses d3.forceSimulation for layout, drag interactions, and zoom, with SVG rendering for all elements.

Force Directed Graph

This example pairs a force-directed graph with an interactive adjacency matrix. The graph uses d3.forceSimulation with forceLink, forceManyBody, and forceCenter to layout nodes, and supports dragging. Clicking a matrix cell highlights the corresponding graph link, while the matrix also shows the dataset’s structure from the infect-dublin.edges file. The code uses d3.csv, d3.select, and reorder.js utilities for matrix permutation.
