<｜begin▁of▁sentence｜>### Instruction:
As a wedding planner, my client has provided me with a list of recommended vendors for their wedding, along with information about their specialties and pricing. I need to organize this information and create a visual representation of the vendor network to better understand the connections and potential collaborations among them. Using the igraph Graph.DataFrame method, I aim to generate an undirected graph that showcases the relationships between the vendors. The graph will help me identify clusters of related vendors and streamline the coordination process for the wedding event.
### Response:
