Dear all,
I am now doing a logistics project on travelling sales person.
I need to put nodes on my map to show the users the locations of some buildings. How do I write the code?

Is there any way to highlight the road between many nodes? For example. if I click on node 1 and node 5, the roads between node 1, passing through node 2-4 and ending at node 5 will be highlighted in red?

Thank you for the help.
