I don't have sufficient context provided to write an accurate overview. While you've indicated this is a Wikimedia category about "Rivers by continent," you haven't provided the actual content, description, or details about the category itself that would allow me to write an accurate and neutral overview based only on what's given. To complete this task properly, I would need the actual category page content or description.
