This example demonstrates how to update a force-directed graph when a user action loads a new dataset, using D3 v4’s enter-update-exit pattern. A button swaps between two JSON datasets containing nodes and links from a character network. The code uses `d3.forceSimulation`, `d3.forceLink`, and `d3.forceManyBody` to compute layout, while SVG circles and lines are bound to the data. Dragging is enabled via `d3.drag`, and the simulation restarts with new data when the dataset changes.

AI-generated description

Sometimes you find situations in which some user action results in loading a new dataset for your force-directed graph. This update action may result either in the display of a completely new force-directed graph or a subset of such graph. To address this need, this is my approach using the enter-update-exit pattern for the force-directed graph in D3.v4.

It seems to work pretty decently, but if you find any bugs or suggestions, please feel free to tell me.

Modifying a Force Layout

This example demonstrates adding and removing nodes and links from a force-directed graph, built with D3 v4’s `d3.forceSimulation` and rendered as SVG. The graph starts with three disconnected nodes, then cycles every second: connecting them in a loop, removing node C with its links, and then re-adding them. The code uses the general update pattern with data joins, keyed by node ID and link source-target pairs. Simulation forces include `d3.forceManyBody`, `d3.forceLink`, `d3.forceX`, and `d3.forceY`, with `alphaTarget` and `alpha` controlling restarts.

D3 v4 - force layout

This example demonstrates a force-directed graph layout using D3 v4's physical simulation API. The visualization shows 100 labeled nodes connected by random links, with node sizes varying between 8 and 28 pixels. The simulation applies multiple forces—link attraction, collision avoidance, many-body repulsion, and centering—to position the nodes dynamically. Dragging nodes with the mouse temporarily restarts the simulation with higher alpha, allowing interactive manipulation of the network. The code uses `d3.forceSimulation`, `d3.forceLink`, `d3.forceCollide`, `d3.forceManyBody`, and `d3.drag` to render SVG circles and lines, updating positions on each simulation tick.

Modifying a Force Layout

This example demonstrates how to add and remove nodes from a force-directed graph over time. Using D3 v4, it starts with three connected nodes (A, B, C) and, after a delay, adds three new nodes, then removes and later re-adds node B with its links. The visualization relies on `d3.forceSimulation` for physics and data joins to update the SVG circles. The code uses the general update pattern with `enter()`, `merge()`, and `exit()` to handle dynamic changes, while CSS classes style nodes distinctly.

D3 v4 - force layout

This example demonstrates a force-directed network layout of 100 nodes and 100 links, rendered as animated SVG circles and lines. The visualization uses d3.forceSimulation with forces for link attraction, collision detection, many-body repulsion, centering, and x/y positioning. Users can drag nodes within the 900×500 pixel graph area, with the simulation’s alpha target adjusting during interaction. The layout updates every tick, repositioning nodes and links based on the simulation state.

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.

Force-directed Layout

This example shows a force-directed network layout of a graph dataset from the Network Data Repository. Nodes appear as orange circles, with gray links connecting them; hovering over a node displays its ID in a tooltip. The visualization uses D3.js v6 with `d3.forceSimulation`, `d3.forceLink`, and `d3.forceManyBody` to compute node positions, while `d3.drag` enables interactive node repositioning. Data is loaded from a CSV file, and the SVG rendering updates continuously during simulation ticks, with node colors assigned via `d3.scaleOrdinal`.

Modifying a Force Layout

This example shows a small force-directed graph with three nodes, A, B, and C, that repeatedly changes structure over time. It initially displays three isolated nodes; after one second, the nodes form a triangle of links, then node C is removed with its connections, and later re-added, cycling every second thereafter. Built with d3.v4, the code uses `d3.forceSimulation` for layout physics and applies a general update pattern with `node.data` and `link.data` to join dynamic datasets. The SVG render updates each tick via the simulation's `on("tick", ticked)` callback, repositioning circles and lines accordingly.

Enter-Update-Exit in Force Layout

This example demonstrates how to apply the enter-update-exit pattern to a D3 force layout, where node and link positions update continuously on each tick. A user-triggered update generates new random data, merges it with existing nodes, and maintains old node positions across re-renders. The code uses d3.layout.force and underscore.js to manage data, with SVG circles and text for nodes and lines for links. Entering and exiting elements are handled through d3 data joins with key functions, while existing nodes preserve their coordinates via the maintainNodePositions function.
