Best way to visualize line data on maps

I'd like to show certain events on Google maps (or other software) any pointers how to do this?

Points (lines actually) would be dynamically loaded from database and presented to the user via web browser.

So what I am trying to do is a Google maps (preferably) with my own custom points(lines), that are clickable and upon clicking more info should be loaded.

I've done something similar with leaflet, but now the requirement is using Google maps or something similar...

Thanks in advance,
Kristjan
