Hi HN, Graph theory had fascinated me as a student. On my first job, I'd briefly worked with Neo4j, a graph database, as part of a proof-of-concept project. At my current gig, I've had the opportunity to delve deep into the world of graph tech, especially databases, over the last one year. Graph-like data models have been around since forever but their mainstream promise is relatively new. A resource which helped me understand the historical as well as fundamental aspects when starting out was the amazing book, "Designing Data Intensive Applications" by Martin Kleppmann. There also exist various resources academic and industry resources around graph tech. But piecing them together to get a holistic picture to evaluate potential use-cases has been an arduous process, to say the least. Hence, I wrote this introductory piece to help anyone interested get started. I'd given a talk on the same topic at PyCon Italy (https://www.youtube.com/watch?v=t0Ra8G8gD-w https://www.youtube.com/watch?v=t0Ra8G8gD-w). I plan to write more on related topics.
