Show location in google map

Hello.
I have data in my table, for example  :

School Name     Latitude        Longitude
School A           xxxxxxxx       yyyyyyy
School B            rrrrrrrrrrr       ttttttttttt

I want to show them in maps,,,so when a user search the school name,,for example School A,, then the user will get a google map with the location of that school. How to do that ? Is that special library,,i already google,but not find right answer yet. Thanks .
