I like sharing my on again, off again side project, CyFHIR. https://github.com/Optum/CyFHIR In healthcare there are a set of open standards for data, messaging, integrating, etc called FHIR. I recognized the unstructured nature of those data standards as graph-like and made this Neo4j plugin for handling FHIR data at the db level. You can import FHIR data directly with optional structural validation and export that data back to json. A graph of the data lets you analyze connections between resources and you can do things like patient similarities on medical histories using graph data science.
