What is fan art?

It seems there are no available podcast clips specifically defining "fan art." However, fan art generally refers to creations made by fans of a particular work of fiction (such as a book, movie, TV show, video game, etc.) that portray characters, scenes, or other elements from that work. These artworks are made by fans to express their admiration and connect with the community of other enthusiasts. This can include drawings, paintings, digital art, and sometimes even three-dimensional creations like sculptures or cosplay.
