Feedback after the test with G6VP visualization platform

[lidongze0629]

Here is the feedback after the test of supported gremlin step with the G6VP visualization platform. I believe some of them may helpful for our GIE engine.

• Query an edge property is not supported yet.

g.E(<id>).valueMap()

• Could the result of expandPath operator carry the edge information? It'll be helpful for graph visualization. Thanks for @BingqingLyu, a new option ALL_E may be a good solution.

g.V().both("1..3", "knows").with('RESULT_OPT', 'ALL_E')

• Now, the result of label operator is a list of numeric, which may be confusing for our user.

g.V().label()
[1,1,1,2,2,2,2]

• The results' order of querying the properties with multiple vertexes is inconsistent with the vertex input. This will cause that we are not able to query the vertex properties in batch

g.V(1,2,3).valueMap()

@lidongze0629 For querying the properties with multiple vertexes, you may try:

g.V().as("a").valueMap().order().by(select("a").by("~id"))

then the results are sorted (by global id).
