You are wrong. An interactive map can be created at
showmymap.com and does not require any programming skills. You can do it even now. If you have an old table of location data. That you forgot about a long time ago now is a good time to get it out of storage. Use it to create your interactive map right now. Or use any free data available online. To see for yourself how such a great program works. Roughly speaking it will do everything for you. You just have to upload your data.
