Apologies if this is in the wrong sub forum, I literally have no idea where to start with this as it's something that I haven't tried or even looked at doing before. Unfortunately I cannot get hold of my webguy I worked with on a project a while ago (on a 6 month trip through the Nepalese mountain! Lucky guy!) He created a map for a project with a line across it which can be changed depending on how far a client has traveled across the map (see image). I am wanting to create something similar for a personal project but for an individual state but I have no idea where to even start. I have googled for what I think it could be explained as and I cannot find anything. I not asking for a full blown solution (unless you want to be so helpful ) But if you know of any tutorials, pages or what parts of a language i should have a look at it would be very very much appreciated!
