Instance Method Details

#build(snapshot) ⇒ Object

Draw order is shuffled so neighbouring stars come from unrelated parts of the codebase: adjacent points would otherwise share a package or a name prefix and read as structure the galaxy does not mean to show. Every ordinal the snapshot used is therefore remapped onto the shuffled order. : (Hash[String, untyped]) -> Hash[String, untyped]
