Create edges (drag & click)

Edge creation is built in, with two interaction styles backed by a live "shadow edge" preview: click-click (click a source node, then a target) and drag-and-drop (drag from one node onto another).

Click Edit Graph (top-right), then Add Edge, and connect two nodes — or just drag from one node to another. Every new edge fires the edgeAdd data event, which here pops a toast.

Options

// Edge creation lives in the full UI mode. Turn it on and the toolbar's
// Edit Graph → Add Edge starts a click-click (or drag) connect session — the
// shadow-edge preview and both interaction styles come for free.
const options = {
    UI: { mode: 'full' }
}

Data

const data = {
    nodes: [
        { id: 'alice', data: { label: 'Alice' } },
        { id: 'bob', data: { label: 'Bob' } },
        { id: 'carol', data: { label: 'Carol' } },
        { id: 'dave', data: { label: 'Dave' } },
        { id: 'erin', data: { label: 'Erin' } }
    ],
    edges: [
        { from: 'alice', to: 'bob' },
        { from: 'alice', to: 'carol' }
    ]
}
