Interactive Directory Map

Hello,

I was just curious if there was anyone out there that had any insight as to how I could build an interactive directory map on my website. I’ve done tons of searching, and havent found much information…any help would be great!

Here are some sites that have a map that I would like to replicate:

https://pgacommons.com/directory/

Thanks ahead of time!
