TITLE: From Neo4j graph to Virtual Reality concept map.
I love Graph Theory and VR, I’ve been using Neo4j since March 2020 and Oculus Rift from march 2019.
The first thing I did in Neo4j is the graphdb for my non-profit association: www.Lecco100.it and I worked a bit on it during online Neo4j courses.
I would like to export my graph into an immersive VR environment, but... can this be done?
The answer is Yes.
Last Year I bought NODA (https://noda.io/), a Mind Mapping VR software you can buy on Oculus or Steam store.
In NODA you can draw a graph with nodes and relationships. Nodes can have Text (labels) and Image, and relationships can have text only. The nodes can have different shapes and color. We don't have properties on nodes and relationships and we don't have directions on relationships.
But...the NODA files are in Json format, a simple Json file.
THE IMPLEMENTATION PLAN
export csv data from Neo4j, one file for nodes and one for relationships;
MATCH (N) RETURN ID(N) AS ID, LABELS(N) AS LABELS, KEYS(N) AS PROPERTIES, N AS DATA
// Relationships list
MATCH (n)-[REL]->(x) RETURN id(n)AS IDA,id(REL) AS IDREL, TYPE(REL) AS RELATION ,KEYS(REL) AS RELPROP, REL AS RELDATA, id(x) AS IDB
Use Excel for create Json code for every row;
THE REAL PROBLEMS WE HAVE
The really interesting problem is the first.
I created a lot of tests and one day I realized that I could use the Excel xy chart to preview the result.
I use z-axis as a layer and the result in NODA is really impressive 🙂
From the beginning of my journey in Virtual reality technology I have seen a lot of opportunity but the only way for making real business is gaming.
I think that a generic way to export graph in VR can be a useful technology for business purposes too , because virtual reality is not just a game.
