What does a polygon graph look like?

Could you elaborate on the appearance of a Polygon graph? How many sides does it typically have, and what kind of data is typically represented within it? Does it have a specific shape that sets it apart from other types of graphs, or does it vary depending on the data being presented? Is there a particular use case or industry where polygon graphs are commonly employed? I'm curious to understand the visual aspect of this type of graph and how it communicates information to its viewers.
