Initial ideas on what shapes these apis will be taking going forward alongside developments in lib.

query w {
  graph(path: "mygraph1", nodeFilter: {}, edgeFilter: {}) {
    # nodeFilter() {}
    # edgeFitler() {}
    
    nodes(nodeFilter: {
      or: [
        {and: [{prop: {field: "a", ge: 1}}, {type: ["a","b","c"]}]},
        {prop: {field: "b", any: [1,2,3]}}
      ]
    }) {
      list {
        name
      }
  	}
	}
}

query w2 {
  graph(path: "mygraph1") {
    # nodePropertyFilter() {}
    # edgePropertyFitler() {}
    
    n1: nodes(nodeFilter: {
      and: [{propFilter: {field: "a", ge: 1}}, {typeFilter: ["a","b","c"]}]
    }) {
      list {
        name
      }
  	}
    
    n2: nodes(nodeFilter: {
      propFilter: {field: "a", ge: 1}
    }) {
      list {
        name
      }
  	}
	}
}

First half of review - looking through the graph tests now

For edges I have the same requests as nodes. Minus you cannot apply an edge filter multiple times and you have already checked that the equality works for lists
