Where in Africa does Tarzan of the Apes by Edgar rice Burroughs take place?

Tarzan of the Apes, by Edgar Rice Burroughs, takes place in the fictional "African jungle," specifically in a region called "the unexplored territory of the Belgian Congo."

While Burroughs never pinpoints an exact location, he describes a dense, primordial jungle teeming with exotic animals and unexplored tribes.

It's important to note that the Belgian Congo (now the Democratic Republic of the Congo) was a real colonial territory at the time Burroughs was writing. However, he uses it as a setting for his fictionalized jungle world, which doesn't necessarily reflect the actual geography or culture of the region.
