6 years ago I had an order for a website with vector interactive map. At that time there were no javaScript libraries which could easily create a map from SVG file - so I created my own. As it often happens - client didn’t pay for my work. I didn’t want to throw out my code - so I started to look for any ways to get at least small profit from it. I uploaded my javaScript plugin to CodeCanyon, gave it a simple name “MapSVG” and to my big surprise after a few weeks my account was filled with more money than I asked from the client who didn’t pay me. MapSVG quickly became my main project and I’m still constantly improving it: http://mapsvg.com
