This example demonstrates a force-directed graph constrained within a fixed rectangular boundary. It visualizes character relationships from *Les Misérables*, with nodes colored by group and connected by gray links. The simulation uses the `d3.layout.force` API, and during each tick event, node positions are clamped so their centers remain within the SVG canvas bounds, accounting for a fixed radius. The graph is rendered as SVG circles and lines, with data loaded from a JSON file.

AI-generated description

This D3 example shows how to constrain the position of nodes within the rectangular bounds of the containing SVG element. As a side-effect of updating the node's cx and cy attributes, we update the node positions to be within the range [radius, width - radius] for x, [radius, height - radius] for y. If you prefer, you could use the each operator to do this as a separate step, rather than as a side-effect of setting attributes.

Bounded Force Layout - very tightly packed

This example demonstrates a bounded force-directed graph layout using D3.js. Nodes from the Les Misérables co-occurrence dataset are tightly packed within a rectangular boundary, constrained by updating their cx and cy attributes to stay within the [radius, width - radius] and [radius, height - radius] ranges. The force simulation continuously repositions nodes while enforcing these bounds, resulting in a dense, space-filling arrangement. Node colors encode community groups, and links represent character co-occurrences, creating a compact, legible network visualization in SVG.

Bounded Force Layout

The visualization shows a bounded force-directed graph of the character co-occurrence network from *Les Misérables*, with nodes restricted to stay within the rectangular SVG canvas. The code leverages the custom `d3.layout.force` API from D3 v3 to simulate the physics, while the `tick` callback clamps each node's `cx` and `cy` attributes to the range `[radius, width - radius]` and `[radius, height - radius]`. The graph reads from a `graph.json` file, and the force simulation is driven by `force.drag` for user interaction.

Labeled Force Layout

A labeled force-directed graph displays character relationships from *Les Misérables*, with each node represented by a GitHub favicon image and a text label. The D3 v3 layout (`d3.layout.force`) simulates physics with gravity, charge, and link distance to position nodes, while SVG lines depict connections. The code loads `graph.json` containing nodes and links, then updates node transforms and link coordinates on each tick event.

29.Force-Directed Graph

This example shows a force-directed graph of character co-appearances in *Les Misérables*, with nodes colored by group membership and link thickness scaled by interaction weight. Using D3 v4, it loads data from `miserables.json` and runs a `d3.forceSimulation` with `d3.forceLink`, `d3.forceManyBody`, and `d3.forceCenter` to compute positions. Nodes and links render as SVG circles and lines, and the visible `ticked` function updates their coordinates. The code also wires up `d3.drag` handlers to let viewers reposition nodes.

Grouped Force Layout

This visualization uses a grouped force layout to cluster the character network from *Les Misérables* by community. Draggable nodes are colored by group, with links showing connections, while a Voronoi overlay dynamically partitions the space to visually reinforce each cluster’s territory. The simulation runs on `d3.forceSimulation` with link and charge forces, and custom logic on each tick adjusts node positions toward their group’s centroid. The Voronoi cells, rendered as SVG paths via `d3.voronoi`, update continuously as the layout settles or as users drag nodes.

Force Directed Graph - Simple

This example shows a simple force-directed graph with a small dataset of character relationships from Les Misérables, rendered as SVG circles in D3 v5. Each node is a character, colored by group using `d3.scaleOrdinal` with `d3.schemePaired`, and hover text reveals the character’s id. The layout is driven by `d3.forceSimulation` with link, charge, and center forces, while nodes are draggable via `d3.drag`. The data is loaded from a CSV file using `d3.csv` with `d3.autoType`, and the code also builds a hierarchy from flat data using `d3.rollup` and `d3.hierarchy`, though links are not displayed.

Force-Directed Graph

A force-directed graph visualizes character co-occurrence in *Les Misérables*, with nodes positioned so related characters cluster together. The simulation uses d3.forceSimulation with link, charge, and center forces, while nodes are draggable circles colored by cluster and links are lines with stroke-width scaled by co-occurrence value. The code loads data from a JSON file and renders everything as SVG.

Force-Directed Layout

This example visualizes the character co-occurrence network from *Les Misérables* using a force-directed layout with animated node and link appearance. Nodes fade in sequentially, and links become visible only after both connected nodes have appeared. The code uses D3’s `d3.layout.force` for physics simulation and SVG circles and lines for rendering, with chained `transition()` calls and `delay` timing to stagger the entrance. Node color encodes group membership via `d3.scale.category20`, while link thickness reflects the edge value.
