This example visualizes energy flows between sources and uses as a bounded force-directed layout, with nodes arranged in vertical columns based on a cluster depth value. The graph shows citation relationships among publications on race and IQ, using circle nodes and connecting lines rendered in SVG. Built with D3 v3 and Vue, the code uses `d3.layout.force` with a custom tick function that constrains node positions within the SVG bounds and adjusts vertical placement by cluster. A simple D3 tooltip appears on mouseover, and the data comes from a local `graph.json` file.

This example takes <a href='http://bl.ocks.org/bjtucker/'>bjtucker</a>'s block: <a href='http://bl.ocks.org/bjtucker/151f6344ffd02105a67a'>Bounded Force Layout - force rank by group</a> and swaps out the dataset, showing energy flows from source to use.

This example also adds a Simple D3 tooltip. Hat tip to biovisualize for that bl.ock.

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.

Wrote the each operator step described above, but used tick to settle groups into separate ranks. -bjtucker

Bounded Force Layout - Columns by Depth

This example uses a bounded D3 force layout to visualize energy flows from source to use, with nodes colored by depth and positioned in columns according to their hierarchical level. The code applies a custom tick function that nudges nodes toward depth-based x-coordinates while constraining them within the SVG bounds, creating a structured layout. It uses d3.svg.axis-free SVG rendering with d3.layout.force, D3 v3, and a simple D3 tooltip on mouseover showing node names. The dataset is a graph of energy production and consumption categories with weighted links.

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 Columns : Creating Reusable Charts

This interactive network diagram displays energy flows between sources, conversions, and end-use sectors using a bounded force-directed layout. Built with D3.js (v3) and SVG, it supports real-time parameter adjustments via sliders, letting users modify node radius, gravity, and charge to reposition elements. The chart includes a tooltip and color-coding by depth, while its modular configuration object demonstrates a reusable pattern for customizing charts through public APIs.

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.

Circular Force-Layout

This circular force-layout visualization maps a network of interlinked nodes, with node size and color encoding attributes like total current and type, respectively. Rendered with D3 v4's force simulation, the SVG animation reveals clustering and directional relationships through directed links. Data is loaded from CSV and JSON sources, and the circular layout emerges from a custom gravity force that pulls nodes toward predefined cluster centers.

Force-Directed Graph

A force-directed graph shows citation relationships among academic papers on intelligence and race, with nodes representing publications and links indicating citations. The visualization uses D3 v4's `d3.forceSimulation` with link, charge, and centering forces, and renders continuously to a Canvas 2D context. Node positions update on each simulation tick, drawing links as gray lines and nodes as white-stroked circles. Data comes from the embedded `miserables.json` file, which includes paper metadata like authors, year, and citation scores.

Directional Force Layout Diagram with node colouring

This interactive graph displays a directional force layout diagram, visualizing the relationships between characters as node connections. The example builds on the basic and highlighting versions by coloring each circular node distinctly using a categorical color scale, while links have varying opacity based on their weight values from the `force.csv` data source. The D3.js code uses the `d3.layout.force` API to simulate the physics, animating the SVG paths and nodes. Users can click to enlarge nodes and text, or double-click to restore them.

How to D3 Force Directed Layout Graph

This example demonstrates a force-directed layout graph using D3.js (v5). Nodes and links are rendered as SVG elements, with the graph's structure implied by the bundled JavaScript. The code uses D3’s built-in force simulation (d3.forceSimulation) to position the connected nodes naturally, while the stylesheet defines the visual appearance of the nodes as grey circles and the links as grey lines. The data is not explicitly shown, but the layout emerges from the simulated forces between connected nodes.
