This chart is intended to be used with reference to ZaidusRecon's map shared to Reddit here.
I created this in response to the Gen I map created by Ryumaster shared to Reddit here, as it only covered Red/Blue and didn't account for the changes made in Yellow.
Hopefully someone can use this information to create a map similar to what Ryumaster made for Red/Blue, as the visual map is such a helpful way of seeing where everything is!
Note this chart has been created based on the information available on Bulbagarden and two different online stat calculation tools. I apologize if any errors have snuck in; I have manually tested some values but most are only calculated and not checked.
