Hi,  
I am trying to extract features from graph given as a JSON file and then use these features to train and test a certain task. how do I go about doing this?

Relative to the training and testing, beats me; depends entirely on what you're trying to get out of the data.

To begin the process though, use `apoc.load.json` to load the JSON URL. You'll get an object in memory which you can then process with cypher to create a graph. What you do with the graph then is up to you. [Neo4j APOC Procedures User Guide](https://neo4j-contrib.github.io/neo4j-apoc-procedures/#load-json)
