The goal of the Covid19-GraphQL project is to look into building GraphQL schema for open-source projects that are developing API or databases for Covid19 data.
To start with, check out CovidGraph! They're using Neo4j, so I've started putting together a GraphQL schema so we can use neo4j-graphql-js with their db.
Playground deployed with Zeit:
Also, check out the CoronaAPI! They're putting together a lot of data scraped from various state resources.
