Investigate how graph databases/graph representations can improve storing the NFAs

[tdauth]

The NFA can be represented by a directed graph but do we have any weights or do we need specific graph algorithms?

Visualization can also be done with graph file formats:

Or with the graph database:

Graph database use custom query languages such as https://en.wikipedia.org/wiki/Cypher_Query_Language. These are used for querying and updating the graphs.
Neo4j allows CQL transactions via REST: https://neo4j.com/docs/developer-manual/current/http-api/

Graph databases provide many features but the legacy implementation only creates a temporary NFA.
Explicitly required features should be added to the custom implementation.
