Hosting a biomedical graph online

Hey there,
I am just curious if there is a good way to host a biomedical graph online. my intention is to make such a graph public for others to use however I am just a student and can not pay thousands of dollars for a paid service. the graph has around 50000 nodes and 300000 relationships.
does neo4j have a free hosting service that can be used to make some graphs available to others if they want to mine on their own or verify the results of papers published about those graphs?

I appreciate any input.


your graph is a little larger than the free tier
