This interactive force-directed graph visualizes relationships between people and database concepts, with nodes colored by category and labeled links showing connection types. Built with React and D3 v4, it uses `d3.forceSimulation` with charge, center, and collision forces to position nodes. Clicking a node highlights its immediate connections by dimming unrelated elements, implemented through React lifecycle methods and D3 selections that update circle and line opacity. The data loads from a local JSON file containing named nodes and typed links.

Updated React+D3, Approach #2

This interactive network visualization demonstrates an approach to integrating React and D3 for rendering force-directed graphs. Clicking a node highlights its direct connections (neighbors and links) while dimming all others. The example uses D3's force simulation to compute node positions and React for component state and rendering, with SVG circles and lines for the graph. Data updates randomly generate new nodes and links while preserving existing node positions, and the version prop triggers re-renders. The visualization explores a hybrid pattern where D3 handles simulation and DOM manipulation while React manages the component lifecycle and interaction state.

Force Layout

This example demonstrates an interactive force-directed graph built with React and D3 v6. A hierarchical dataset is flattened into nodes and links, then rendered as circles and lines using SVG. The simulation uses `d3.forceSimulation` with center, charge, collide, and link forces. Moving the mouse dynamically adds `forceX` and `forceY` forces that pull nodes toward the pointer, with strength varying by node depth. Clicking applies a `forceRadial` orbit force around the clicked point and draws a green circle to indicate the orbit radius.

This example demonstrates a React-based data visualization built with D3.js, showing an interactive force-directed graph. The code employs `d3.forceSimulation` to position nodes and links, with forces for charge, collision, and centering, while rendering the network through SVG elements. It visualizes hierarchical data using a cluster layout, with nodes colored and sized according to their depth and connection counts. The visualization updates dynamically as the simulation runs, with drag interactions enabled via `d3.drag`, allowing users to move nodes and observe the spring-like link forces in real time.

This interactive network diagram uses a force-directed layout to show relationships between six nodes, with link thickness encoding connection strength. The visualization reads data from a JSON file containing nodes and links, then renders circles and lines as SVG elements. Built with React and D3 v4, it uses `d3.forceSimulation` for physics-based layout, `d3.forceLink` for link constraints, `d3.forceManyBody` for node repulsion, and `d3.forceCenter` for centering. Nodes are draggable via `d3.drag`, allowing users to manually reposition elements while the simulation continues.

A8 - node-link diagram with force-directed layout

This example shows a force-directed node-link diagram of the Zachary Karate Club social network, with orange nodes and gray edges. It uses the D3 forceSimulation API to compute the layout through charge, link, and center forces, updating the SVG positions on each tick. Node labels appear in a tooltip on mouseover, built with D3’s selection and transition API. The graph renders as an SVG with animation, driven by the react framework, and the data is loaded from a remote CSV file.

Force Directed Graph

This visualization presents a network of interconnected nodes, with each node colored by its assigned group and links showing the connections between them. It combines a force-directed node-link diagram with an adjacency matrix display, revealing both the spatial clustering of relationships and the overall network structure. The force layout is built with `d3.forceSimulation`, including `d3.forceLink` and `d3.forceManyBody`, while user interactions like node dragging, zooming, and hover effects are handled through D3’s drag and zoom APIs. The adjacency matrix uses `d3.scaleBand` axes to map node IDs, and both SVG canvases render the data with animation driven by the simulation tick events.

Force

This interactive network visualization shows a force-directed graph of connected nodes, with larger colored circles representing main hubs and smaller ones as children. Using d3.forceSimulation's many-body and link forces, the graph settles into a clustered layout. Users can drag nodes, which restarts the simulation. The SVG renders colored edges and circles, with labels for main nodes, built with d3.v6 in a React framework.

Force directed graph for D3.js v4 with labelled edges and arrows

This force-directed graph visualizes a small network of four entities—people and databases—with edges labeled by relationship type (e.g., "KNOWS", "FOUNDED") and directional arrows. Built with D3.js v4, it uses `d3.forceSimulation` for layout, SVG `<line>` elements for links, and `<textPath>` elements along invisible paths to place edge labels. Nodes are colored via `d3.scaleOrdinal` and support drag interaction. Data comes from an external `graph.json` file, with labels positioned and flipped to avoid overlap.
