Importing Output graphml file into Neo4j

Hi @dirkbaechle 

I have a graph in the form of dot file and I wanted to import that graph into Neo4j. I couldn't find a direct way to import dot file into Neo4j but there is a direct way to import graphml file into Neo4j.

Is it possible that the graphml file generated from the dot file using this repository can be directly imported in Neo4j? Can have tried it?
