Find Efficiency of Pokemon

Pick a pokemon from the dropdown menu, that will show you each of the spawning areas where that pokemon is present.
Each area will have a rank and a color gradient, 1 and green being the best.
Hover an area to see each of the pokemon's types and a percentage associated with them. That percentage tells you how efficient it is to hunt that pokemon by using a sandwich of that type in that area.
Craft a lvl 3 sandwich and go around the selected area in-game to look for the spawns

Find Efficiency of Type (beta)

Pick a type from the dropdown menu.
The map will show every area that has one pokemon with 100% efficiency for the type you picked.
This is most useful if you want to target a type for multiple pokemon during one sandwich.

All of the raw data was obtained from https://www.serebii.net, used for calculations and redrawn on their map.

Fixed area calculation issue with scatterbug and sawsbuck's different forms.
When clicking an area in the map you can now see the other pokemon that spawn in that same area.

Split pools for scarlet and violet and added select for version. Type efficiency calculations should be as accurate as possible.

Changed spawn pools. All version exclusives and shared pokemon are in one pool but paradox are still in separate pool. Thanks to u/BadAimBoy for pointing this out.
Added changelog.
