The new graph database plugin for IntelliJ provides useful developer features such as syntax highlighting and autocompletion for Cypher, allowing developers to work efficiently with graph databases. The plugin supports Neo4j 3.4+ (Bolt), including AuraDB, and is maintained by Alberto Venturini. This week also marks the start of various exciting events and projects related to graph databases, including Neo4j Live, GraphSummit Series, and LangChain's integration with a graph database. Additionally, Kineviz shares insights on GPT4-powered querying in GraphXR, allowing developers to ask questions about their data and get relevant results in seconds.
