Ask HN: Have you ever used a JSON-based format for representing graphs/networks?

I'm working with graph data and want to store it in a JSON-based format. Objectives are to allow analysis outside a graph DB and import into one (Neo4j, AWS Neptune, Janusgraph) when required. I came across a few formats (listed below) but I couldn't find user stories as such. I'm very interested to know if you've ever tackled with a similar problem statement. Graph JSON Formats: - GraphSON (http://tinkerpop.apache.org/docs/3.4.1/dev/io/#graphson) - JSONGraph (http://jsongraphformat.info/)
