How to access novias node relationships data in the labels function?

[ra-haik]

labels:
            {
                ID: {
                    label: "name",
                    identifier: "ID",
                    [NeoVis.NEOVIS_ADVANCED_CONFIG]: {
                        static: {
                            color: "#97c2fc",
                            shape: "dot",
                            size: 5,

                        },
                        function:  {
                            size: (node) => {           
                                return // how to access node.reletioships so that I can count the properties.visits.length like below?
                            }
                        },
                    },
                },
            },
            relationships: {
                TRAFFIC: {
                    [NeoVis.NEOVIS_ADVANCED_CONFIG]: {
                        static: {
                            width:1,
                        },
                        function: {
                            width: (node) => {
                                return node.properties.visits.length;
                            }
                        },
                    },
                },          
            },

You should do it in the cypher as neo4j doesn't return a way to get to the relationships in the object

I didn't touch cypher in a long time so need to search how I did it back than

Umm... Not really, but after the complete event you can to use it directly and if you get stuck you can continue ask here 😅 the tests kinda use it to get data, and neovis.nodes.update{id: id, newdata} should be pretty much the api to update it

complete event

"complete event"

For some reason it is not working for me, the viz.node does not contain anything when the event is raised

      const viz = new NeoVis(config);
        viz.render();

        viz.registerOnEvent('completed', () => {
            console.log("Graph visualization completed.");

            // Update node size based on relationship data

            console.log(viz.edges);

            console.log(viz.nodes); 

            for (let nodeId in viz.nodes) {
        // noting here
            }
        });

Thats... Really weird, it makes no sense (I think maybe you can't iterate over it but it is not empty?)
https://visjs.github.io/vis-data/data/dataset.html maybe try vis.nodes.forEach?

Thank you very much for your help, here is the code that is working.

        const viz = new NeoVis(config);
        viz.render();

        viz.registerOnEvent('completed', () => {
            console.log("Graph visualization completed.");

            viz.nodes.forEach((node) =>
            {
                let newSize = 0;

                if (node.group == 'ActiveDirectoryDomain') {
                    viz.nodes.update({ id: node.id, size: 10 });
                }
                else if (node.group == 'User') {
                    viz.nodes.update({ id: node.id, size: 5 });
                }
                else {

                    viz.edges.forEach((edge) => {
                        if (edge.from === node.id || edge.to === node.id) {
                            newSize += JSON.parse(edge.raw.properties.visits ?? '[]').length;
                        }
                    });

                    viz.nodes.update({ id: node.id, size: newSize });
                }
            }); 
        });

That's really weird you need to parse the array, but other than that Im glad managed, also you can use vis.edges.get({to: node.id}) to get all edges instead of iterating over all of it 😅

Is it possible to use array type in neo4j, I don't see it on the list?

Not sure what app are you using, but in the cypher you can do things like

MATCH (a)
SET a.a = [1,2,3,4]

And it should work

Thanks, was able to fix it, the issue was with the data loading tool.
