Wicket is a lightweight Javascript library that reads and writes <a href="http://en.wikipedia.org/wiki/Well-known_text#Geometric_objects" target="_blaknk">Well-Known Text (WKT)</a> strings. It can also be extended to parse and to create geometric objects from various mapping frameworks, such as <a href="http://http://leafletjs.com/" target="_blank">Leaflet</a> and the Google Maps API.
