How to use the vis-network/peer.Network function in vis-network

          size: 25,
          image: switchImg
        }
      }
    }

    // Create and fill datasets
    const nodes = this.nodes = new DataSet()
    const edges = this.edges = new DataSet()
    // It's necessary to load the items now, otherwise the network would be labeld as ready before the items are visible.
    this.replaceItems()

    // Create the network
    const net = new Network(this.$refs.vis, { nodes, edges }, options)
    this.net = net

    // Some labels contain placeholders for info from connected nodes.
    // Therefore this can't be done before the topology is built.
    this.updateLabels()

    this.cleanUpCallbacks.push(this.$store.subscribe(({ type, payload }, { data }) => {
      ;(this.storeActions[type] || (() => {}))(payload, data)
