 What is GraphQL ?

It is a query language for API 

SOAP :XML

RESTful:JSON

GraphQL:JSON

Each address represent resource in case of SOAP API 

/users/john

it will return all details associated with this resource

Incase of RESTful api it is focused on resource based so very type of data to extract we can use different request.

/users/john/address

/users/john/bankaccount

GraphQL :Query based approach to fetch data only one request needed to fetch needed data .

Example : 

query {

  cars {

    id

    make

    model

    year

  }

}

The query is requesting information about cars.
Within the cars field, the query is asking for the id, make, model, and year of each car
