label
type: lblString, default: "\N" (nodes) , "" (otherwise)
Text label attached to objects.
If a node’s shape is record, then the label can
have a special format
which describes the record layout.
Note that a node’s default label is "\N", so the node’s name or ID becomes
its label.
Technically, a node’s name can be an HTML string but this will not mean that the node’s label will be interpreted as an HTML-like label. This is because the node’s actual label is an ordinary string, which will be replaced by the raw bytes stored in the node’s name.
To get an HTML-like label, the label attribute value itself must be an HTML string.
Example: Van Gogh Paintings
graph {
label="Vincent van Gogh Paintings"
subgraph cluster_self_portraits {
label="Self-portraits"
spwgfh [label="Self-Portrait with Grey Felt Hat"]
spaap [label="Self-Portrait as a Painter"]
}
subgraph cluster_flowers {
label="Flowers"
sf [label="Sunflowers"]
ab [label="Almond Blossom"]
}
}
