A teeny-tiny-weeny Graphviz-emitting library written in Swift available as a Swift Package.
Mostly used as a dependency by my other OSS projects.
Sample usage:
let viz = Graphviz()
viz.createNode(label: "node1", groups: ["Subgroup"])
viz.createNode(label: "node2", groups: ["Subgroup", "Inner Subgroup"])
viz.createNode(label: "node3", groups: ["Subgroup", "Inner Subgroup"])
viz.addConnection(
fromLabel: "node2",
toLabel: "node3",
attributes: [
"label": .string("connection label"),
"color": .string("red"),
"penwidth": 0.5,
]
)
print(viz.generateFile())prints:
digraph {
graph [rankdir=LR]
label = "Subgroup"
n1 [label="node1"]
subgraph cluster_1 {
label = "Inner Subgroup"
n2 [label="node2"]
n3 [label="node3"]
n2 -> n3 [color="red", label="connection label", penwidth=0.5]
}
}
