An interactive, draggable, SVG based network graph visualization component for Vue 3.
Basic Usage:
1. Import and register the component.
import VNetworkGraph from "v-network-graph" import "v-network-graph/style.css" Vue.use(VNetworkGraph);
2. Add the v-network-graph component to the template.
<template>
<v-network-graph
:nodes="nodes"
:edges="edges"
/>
</template>
3. Prepare your node & edge data as follows:
import { defineComponent } from "vue"
export default defineComponent({
setup() {
const nodes = {
node1: { name: "Node 1" },
node2: { name: "Node 2" },
node3: { name: "Node 3" },
// ...
}
const edges = {
edge1: { source: "node1", target: "node2" },
edge2: { source: "node2", target: "node3" },
// ...
}
return { nodes, edges }
},
})
4. Default component props.
