This example adapts d3-drag to a d3-force simulated network graph, freezing nodes in place after the layout settles. On drag start, the targeted node is fixed to the pointer via `simulation.fix`; when the gesture ends, it remains fixed, and the simulation’s "end" event triggers a `settled` function that pins all nodes at their final positions, keeping the graph cold. The visualization uses the classic *Les Misérables* co-occurrence dataset, with gray links and circles colored red when fixed. The author is FrissAnalytics, built with D3 v4 and rendered using SVG.

AI-generated description

This example demonstrates applying d3-drag to a force-directed graph computed using d3-force. When the drag gesture starts, the targetted node is fixed to the pointer; it is released when the gesture ends.

Unlike 'Force Dragging I', the simulation remains “cold” after it has settled. All nodes retain fixed positio.

Compare to the Canvas version.

Force Dragging III

This example shows a force-directed graph rendered with Canvas, where nodes represent characters from *Les Misérables* and links show their co-occurrence in Victor Hugo’s novel. The graph is computed using d3-force, with node colors mapped by group through an ordinal color scale. Dragging a node with the mouse fixes it to the pointer while the simulation’s alpha target is raised to 0.3, heating up the layout for smoother interaction; releasing the node unfixes it and returns the alpha target to zero. The visualization demonstrates how d3-drag can be combined with d3-force in a canvas-based rendering, with nodes and links redrawn on every tick for responsive, interactive exploration of the network.

Force Dragging I

This interactive force-directed graph visualizes character co-appearances in *Les Misérables*. Users can drag any node, which fixes it to the pointer during the gesture while the simulation's target alpha is set to a non-zero value, "heating" the layout to emphasize the drag's effect. The graph uses `d3.forceSimulation` with link, many-body, and center forces, while `d3.drag` manages the drag interactions on SVG circles. Node and link positions update on each simulation tick, and the underlying data comes from `miserables.json`.

Force Dragging III

This example shows an interactive force-directed graph of character co-occurrence in *Les Misérables*, rendered as nodes and links on a Canvas. Users can click and drag any node to reposition it, which temporarily fixes that node to the pointer and reheats the simulation. The code uses d3.forceSimulation with link, charge, and center forces, while d3.drag handles the drag gesture. Data comes from the bundled miserables.json file, and the visualization redraws on each simulation tick.

29. force drag 1

A force-directed network graph displays character relationships from Les Misérables, with nodes representing characters and links showing their connections. The visualization uses d3.forceSimulation with link, charge, and center forces to position the nodes, while the links are rendered as SVG lines and nodes as circles. Users can drag any node to interact with the layout, as the code enables d3.drag on the circles with start, drag, and end handlers that fix and release the dragged node's position during the simulation.

(d3v4) Force Layout w highlights

This example shows a force-directed network graph of character interactions from *Les Misérables*, rendered as SVG nodes and links. Hovering over a node or link highlights its connections by fading unrelated elements, while a tooltip displays names, groups, and link strength. Dragging nodes repositions them, and double-clicking releases them from the fixed position. The visualization uses d3.forceSimulation with link, charge, and center forces, plus d3.drag for interaction and d3.schemeSet3 for coloring nodes by group.

canvas + drag + zoom + fixed nodes

This example shows a force-directed network graph rendered on a canvas, where nodes settle into a fixed layout once the simulation ends. Users can drag individual nodes and zoom or pan the entire visualization with the mouse. The code uses D3 v4’s d3.forceSimulation with charge, link, and centering forces, and handles canvas rendering through the 2D context with transform scaling and translation. Node and edge data are loaded from an external JSON file, with pre-defined edge connections.

D3 v4 - force layout

This example shows a force-directed graph with 100 randomly generated nodes and links, rendered as SVG circles and lines. The code builds the network using `d3.forceSimulation` with forces for link distance, collision, charge, centering, and X/Y positioning, then updates node and link positions on each tick. Nodes are draggable via `d3.drag`, and drag events adjust the simulation’s alpha target to restart or settle movement. The data is synthesized in the script, and the visualization initializes from a blockbuilder.org fork.
