Most basic example of optimization with 2 or 3 points?

Hello all.

I need to make a purchase decision for my company.

One of our staffers has to load about 50 locations each day and find the shortest route between those points.

I’ve been working with PHP and JavaScript 20 years, jQuery for 10. The only examples I’ve found online are super-robust packages with out comments or documentation. I’m just looking for a simple example with a few points to see how easy graphhopper is to work with.

Can anyone provide the most basic example of routing a small number of points onto a map? I can take it from there.

May thanks to anyone who can help.
