This Winter Challenge aims to encourage developers to create innovative graph models and example queries, focusing on various use cases such as solving complex JOINs, providing recommendations, conducting impact analysis, managing content and assets, and showcasing creative graph search applications. The challenge offers a grand prize of $500 for each of six categories, with the opportunity to participate in the jury for previous winners. Participants have until February 22nd to submit their entries, which will be reviewed and announced shortly after. To aid in the process, Neo4j has launched its GraphGist Portal, featuring a collection of past submissions, and invites developers to share their work using the hashtag #graphgist.
