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.

AI-generated description

Click in the open space to add a node, drag from one node to another to add an edge.
Ctrl-drag a node to move the graph layout.
Click a node or an edge to select it.

When a node is selected: R toggles reflexivity, Delete removes the node.
When an edge is selected: L(eft), R(ight), B(oth) change direction, Delete removes the edge.

Directed Graph Editor

This interactive editor lets users manipulate and design directed graphs. It visualizes nodes as colored circles and edges as straight lines with arrow markers indicating direction. Users can add nodes, drag them to reposition, and create new edges by drawing lines between them. The graph is rendered using SVG and animated with d3.forceSimulation for layout and d3.drag for node interaction.

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 directed graph editor displays nodes and edges that users can drag, select, and modify. The visualization uses d3.forceSimulation for physics-based layout, with SVG circles for nodes and paths for links. Clicking nodes toggles reflexive edges, dragging between nodes creates new links, and dragging on empty space adds nodes. The React framework manages the component structure, while D3 handles the simulation, rendering, and event handling through d3.drag and pointer coordinates.

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 displays a network of nodes and edges that users can create, drag, and connect. The visualization uses a force-directed layout, with nodes represented as circles and edges as lines with arrowheads to indicate direction. The editor relies on D3’s built-in force simulation API to calculate the physics-based positions of nodes and handles mouse interactions directly. The code defines the graph data structure in `app.js` and uses the `d3.forceSimulation` to update the positions of connected nodes dynamically.

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.

Directed Graph Editor

This example shows an interactive directed graph editor where nodes and links can be dragged and selected within a full-screen SVG. The graph uses a force-directed layout via `d3.forceSimulation` with charge and centering forces, rendering nodes as circles and links as stroked paths. Users can add or modify connections, with selected links shown as dashed lines and reflexive edges highlighted. Styling is handled through CSS classes in `graph.css`, while the React-based version integrates these D3 v5 APIs into a component structure.
