There's no reason we can't have both algorithms and methods on `Graph`
which run the algorithm and ignore customization. I'll add this shortly.
> Methods for translating Graphs

> Key: FLINK-3771
> URL: https://issues.apache.org/jira/browse/FLINK-3771
> Project: Flink
> Issue Type: New Feature

>
> Provide methods for translation of the type or value of graph labels, vertex
> values, and edge values.
> Sample use cases:
> * shifting graph labels in order to union generated graphs or graphs read
> from multiple sources
> * downsizing labels or values since algorithms prefer to generate wide types
> which may be expensive for further computation
> * changing label type for testing or benchmarking alternative code paths
