Today it's easy to put an interactive map on a website. You can make a map in Google maps or other mapping software. But how convenient is it to make a map yourself?
If you do not want to waste time on this, it is better to turn to a professional. But if you have enough time to create a map, then it will be quite easy to do yourself with the help of the map maker. I tried to create a map myself, but I didn't have the patience for it. But it's a very interesting thing to do. By creating interactive maps, you learn a programming language.
