Graph Generation

====================

In this problem, you will be implementing a graph generation model using a Graph Variational Autoencoder (GVAE).

**Example:** Given a graph with nodes and edges, generate a new graph with similar structure.

**Constraints:** Use a GVAE architecture with a graph encoder and a graph decoder.

**Note:** You can assume the graph is represented as an adjacency matrix.
