  (2)To ensure that the new Gremlin statement can be executed, please create the graph data schema, use full English, and use Markdown format to output, following the JSON format:
  {

      vertexTypeName: 'replaced with entity A type name', 
      properties: [{
        propertyName: 'replaced with entity property X name',
      }, {
        propertyName: 'replaced with entity property Y name',
      }, //other entity properties
      ]
    }],
    edgeTypes: [{
      edgeTypeName: 'replaced with relationship A name', 
      properties: [{
        propertyName: 'replaced with relationship property X name'
      },{
        propertyName: 'replaced with relationship property Y name'

      vertexPairs:[
        {
          fromName:'replaced with source entity type name ',
