Circular Layout

Overview

Circular layout arranges nodes evenly or at intervals on a circle, and also supports spiral layouts by configuring different startRadius and endRadius. See more circular layout examples or source code.

Usage Scenarios

Circular layout:

Suitable for networks with equal relationships and no hierarchical structure

Spiral layout:

Suitable for implicit hierarchies or time series graphs (such as organizational charts, propagation networks)

Basic Usage

Other settings use the default configuration (layout width and height default to the entire canvas container)

const graph = new Graph({
  // other configurations
  layout: {
    type: 'circular',
  },
});

Options

Property	Description	Type	Default	Required
type	Layout type	circular	-	✓
angleRatio	How many 2*PI between the first and last node	number	1
center	Center of the layout	[number, number]\|[number, number, number]	[`layout width` / 2, `layout height` / 2]
clockwise	Whether to arrange clockwise	boolean	true
divisions	Number of segments on the ring (segments will be evenly distributed, effective when endRadius - startRadius != 0)	number	1
nodeSize	Node size (diameter), used for collision detection	Size \| ((nodeData: Node) => Size)	10
nodeSpacing	Minimum spacing between rings, used to adjust radius	number \| ((nodeData: Node) => number)	10
ordering	Node ordering on the ring, see details	`topology` \| `topology-directed` \| `degree`	-
radius	Circle radius, if set, spiral layout configs `startRadius` and `endRadius` are ignored, see details	number	-
startAngle	Start angle of the layout	number	0
endAngle	End angle of the layout	number	2 * Math.PI
startRadius	Start radius for spiral layout, usage	number	-
endRadius	End radius for spiral layout	number	-
width	Layout width	number	canvas width
height	Layout height	number	canvas height

ordering

Node ordering on the ring

topology: topological order
topology-directed: topological order (directed graph)
degree: order by degree

If not set (null), the order in the array is used directly

radius

If radius, startRadius, and endRadius are not set, the default is Math.min(layout width, layout height) / 2, i.e., fills the entire layout area

Code Examples

Basic Circular Layout

const graph = new Graph({
  // other configurations
  layout: {
    type: 'circular',
  },
});

Spiral Layout

const graph = new Graph({
  // other configurations
  layout: {
    type: 'circular',
    startRadius: 10,
    endRadius: 300,
  },
});
