How to store nested structure in graph database

I am analyzing how to store nested/hierarchical structure in graph database. I want to store like a tree where settings vertex will have two children DigitalInput and Input2 and like in subsequent parameters. Any inputs for which approach I should choose and how?

"properties": {
        "A": {
          "value": "prop1 new value"
        },
        "settings": {
          "DigitalInput": {
            "Input1": {
              "nTransIn1": {
                "tagName": {
                  "value": ""
                }
              }
            },
            "Input2": {
              "nTransIn2": {
                "tagName": {
                  "value": ""
                }
              }
            }
}
