Displaying user information on Google Map on click of the location using node js, express and mongodb

I am doing a small project which takes user information like name, age, location etc and display it on the Google map on click of that location.

I have completed the first part i.e., taking user information using node js, express and Mongo db.

I am not understanding how to go to next part and display that information on Google maps on click of that location.

Any tutorial or pointers would be helpful on how to go forward. Thanks.
