GraphLayout - UI controls for graph visualization. It is powered by Graphviz. Graph visualization is a way of representing structural information as diagrams of abstract graphs and networks. It has important applications in networking, bioinformatics, software engineering, database and web design, machine learning, and in visual interfaces for other technical domains.
To run the example project, clone the repo, and run pod install from the Example directory first.
Xcode 9, iOS 11
GraphLayout is available through CocoaPods. To install it, simply add the following line to your Podfile:
pod 'GraphLayout'Notice, please, GraphLayout doesn't support frameworks.
Create graph, add nodes and edges.
let graph:Graph = Graph()
let node1 = graph.addNode("node 1")
let node2 = graph.addNode("node 2")
let node3 = graph.addNode("node 3")
let _ = graph.addEdge(from: node1, to: node2)
let _ = graph.addEdge(from: node1, to: node3)
let _ = graph.addEdge(from: node3, to: node2)Apply graph layout (Graphviz powered)
graph.applyLayout()GraphView is a view to draw graphs. Set graph property of GraphView.
graphView.graph = graph
graphView.setNeedsDisplay()GraphLayout is UICollectionView layout and data source to display graphs.
let layout = GraphLayout()
layout.graph = graph
layout.setup(collectionView: collectionView)
