So, after interpolation, your string expressions looks like: g.addV("place").property("location", Geoshape.geoshape(Geoshape.getShapeFactory().polygon().pointXY(42.5636137, 1.4294247).pointXY(...).poi

Integrate CustomVertexProgram to janusgraph
Hi Nikita, gremlin console does a lot of imports for you, but does not cover the full JanusGraph and TinkerPop APIs. So, sometimes you have to do an import yourself. In this case: gremlin> import org.

Yes, I forgot that one, VertexPrograms need to be written in java. If you are not familiar with setting up java projects, you can take a look at the examples at: https://github.com/JanusGraph/janusgra

The easiest way is to write your custom VertexProgram for TinkerPop. If it runs in TinkerPop, it will also run in JanusGraph. There are other ways, though, see two examples in: https://github.com/Janu
