Is PancakeSwap part of Binance?

I've been hearing a lot about PancakeSwap recently and I'm curious about its connection to Binance. Could you clarify if PancakeSwap is actually a part of the Binance ecosystem? If not, what's the relationship between the two, and how does PancakeSwap fit into the broader cryptocurrency landscape? As a seasoned investor, I'm always looking to stay informed and make well-informed decisions about my investments, so any insights you can provide would be greatly appreciated.
