Network

Property	Default	Meaning
children	—	Identified elements, direct Edge children, and ordinary graph content
coord	Inferred	[xmin, ymin, xmax, ymax] shorthand for both limits
xlim / ylim	Inferred	Directed data limits, as in Graph
flip-x / flip-y	false / true	Horizontal reversal and Cartesian y-up mapping
padding	0.2	Fraction of each inferred span added on either side
clip	false	Clip painting to the network canvas

Network lays out and places its nodes before connecting them with Edge. Any element with an id is a node: a Node label, a Circle, an image, a stack, or a whole nested Network. Give each one a unique id, and use that ID in an edge's start and end. Edges may appear before their nodes in the source. Source order remains paint order; put edges first to paint them behind nodes.

Edges meet the visible outline of boxes, frames, rectangles, squares, circles, and ellipses, including rounded corners. Every other element connects at the rectangle of its allocation. A TitleFrame's outline spans its overhanging title, so an edge from above meets a centered title. All elements with pos default to a centered anchor. Set anchor="start" to position an element by its top-left corner.

See Positioning for anchor values and the distinction between data positions and local layout lengths.

Node positions use data coordinates. Fonts, frame padding, borders, and arrowheads use ordinary px/em/fractional layout lengths. Changing the canvas size moves the nodes while their labels retain their font size; an explicit node width can wrap its label. Edges attach to the resulting frame after that wrapping finishes.

Sizing and coordinate options follow Graph: a natural network is 480×320, finite offers establish the canvas, and an aspect derives a missing axis. Inference includes the numeric Cartesian components of each child's pos, intermediate edge points, and graphable marks. Positions accept [x, y] or {x, y}; tagged lengths stay local and do not contribute to limits. Inferred padding is a fraction of the data span, so it does not reserve a measured margin for every label. Use explicit limits or surrounding Box padding when you need a particular margin. Use explicit limits for nodes inside nested layouts.

Nodes can be inside Box, Rotate, stacks, or other ordinary layout elements. Network finds their completed connection boundaries through the placement tree, including all offsets and transforms. See Connections through layout. An identified container stays transparent, so edges can reach both a group and the identified elements inside it. Each nested Network has its own ID scope: its own id makes it a single node of the outer network, while its members stay private. Duplicate IDs within one scope and unknown edge endpoints are errors.

Ordinary children work as they do in Graph. Clipping hides paint while retaining overflow and the nodes' connection geometry. Network connects the positions you provide; it does not automatically arrange nodes or avoid intervening obstacles.
