We demonstrate EGG (Evolving Graph Generator), an open-source framework for generating evolving RDF graphs based on finely-tuned temporal constraints given by the user. During the demonstration, we will showcase the highly-expressive constraints that the user can specify in EGG to generate evolving graphs over various real-world use cases, the accuracy and scalability of the generator, and the ease of using EGG in performance comparisons of evolving graph processing systems.
