Neo4j is all-in on, "almost everything looks like (or can be made to look like) a graph, so almost everyone should be using a graph database".

As for those specific figures, I'm guessing there's enough wiggle room in "data and analytics innovations" (emphasis mine) to find or project almost any trend one wishes. What are data analytics innovations? Why, it's the set of things that will see 80% use of graph technologies! "Graph technologies" is also so potentially-vague that it could plausibly be 100% of almost anything related to software.
