I let it slip to a friend that I took some GIS courses before, and he asked me to help him make graphs/charts for him. Being the good friend I am, I agreed, but only if he would buy me lunch.
My old go-to program was Tableau, but it's no longer free (you need to register it with a business or something like that).
I do have access to the entire Adobe Suite, but I doubt that will be useful.
