Force Editor

Directed Graph Editor

This interactive directed graph editor displays a network of nodes and links that respond to mouse events. Users can click nodes to select them, and drag to create or modify connections. The visualization uses D3 v5’s force simulation (`d3.forceSimulation` with `forceManyBody` and `forceCenter`) for layout, while SVG paths and circles render the graph elements. The code styles interactions through CSS classes, including draggable links and reflexive node states.

Graph Editor

This interactive graph editor visualizes small directed graphs using SVG rectangles, text labels, and arrow-tipped lines. Users can drag nodes to fix their positions, and click fixed nodes to release them, allowing free exploration of graph connectivity. The implementation uses D3 v4’s force simulation (`d3.forceSimulation`, `d3.forceLink`, `d3.forceManyBody`, `d3.forceCenter`) and drag behavior (`d3.drag`) to manage node physics. Node and link data are bound to SVG groups and lines, with arrowheads defined via SVG markers. The graph structure is defined in-memory, and the rendering updates dynamically as users interact.

Directed Graph Editor

A directed graph editor demonstrates interactive node-and-link manipulation using a force-directed layout. Users can drag nodes to reposition them, click links to select them, and create new connections with mouse gestures. The visualization renders nodes as colored circles with text labels, while links display directional arrows based on their left and right properties. The implementation uses d3.forceSimulation for physics-based layout, d3.drag for node movement, and SVG markers for arrowheads. Node and link interactions are handled through mouse events, with reflexive edges highlighted as bold black circles.

Directed Graph Editor

This interactive tool lets users create and edit directed graphs by dragging nodes, clicking to add new ones, and selecting edges. It visualizes a force-directed layout using `d3.forceSimulation` with custom link and node elements. The code handles node dragging, edge creation between nodes, and node deletion, with reflexive edges drawn as loops. Styling distinguishes selected links with dashed strokes, while the simulation uses `d3.drag` and `d3.forceLink` to manage interactions and positions.

Directed Graph Editor

This interactive directed graph editor lets users create, drag, and connect nodes with labeled links, highlighting selected edges with dashed styling. The visualization is built using D3 v5's force simulation for node placement and SVG elements for rendering, with graph interactions handled through mouse events in a React application. The code uses `d3.forceSimulation` to manage node positions and link forces, while CSS controls visual feedback such as cursor changes and stroke styles. The graph is displayed in a full-window SVG canvas.

Directed Graph Editor

This interactive tool demonstrates a directed graph editor using React and D3 v5, where users can create and manipulate nodes and edges through direct manipulation. The visualization employs `d3.forceSimulation` to handle physics-based layout, with nodes rendered as circles and links as paths whose thickness and dashed styling indicate selection states. The code utilizes D3’s selection API to bind drag behavior, enabling dynamic node repositioning, while the `graph.js` script dynamically sets the SVG dimensions to the window size. Users can also draw new connections via a dragline interaction, though the implementation details for editing actions are partially implicit in the CSS and script structure.

Directed Graph Editor

This interactive editor demonstrates graph creation and manipulation, showing nodes connected by directed edges with arrowheads indicating direction. Users can add nodes by clicking empty space, add edges by dragging between nodes, and select or modify elements via keyboard shortcuts. The code uses d3.forceSimulation for layout and d3.drag for node repositioning, with SVG paths and circles as the primary rendering elements. The example implements various interaction states, including reflexive edges, directional toggles, and visual feedback for selected components.
