Graph databases have become increasingly popular, with their modern instantiations such as Neo4j and Alchemy.js being well-represented at the O'Reilly-hosted OSCON conference in Portland, Oregon. The benefits of graph visualization are highlighted by Huston Hedinger, Founder and CEO of GraphAlchemist, who notes that it can provide insights into various domains, including social networks and supply chain networks. The Neo4j team successfully engaged with attendees, answering questions about graph databases and even creating an interactive Twitter graph mapping the conference participants' social interactions.
