Ask HN: Graph DB that can produce visuals to replace process flowcharts?

Hi HN - I'm looking to use Neo4j or another graphDB to capture data on how several elements of a process interact. While Neo4j is great for capturing and querying the data; I can't find any tools that would allow me to export the nodes & edges in a structured format so that I could use the exported data to replace our process flowcharts (i.e. - define the direction, adjust visual elements, change fonts, assign specific node positions) Does anyone know of any tools that can do this?
