Need to create a simple webapp to display 2 trees / list, side-by-side, and a way of drawing lines to connect each item from the tree / lists, by dragging a line and dropping on the target item / node. A line will stay drawn, and many lines can be drawn this way. The lines can be removed or remapped to another item / node. While been dragged the target will be highlighted, and once dropped, it will establish a connection. It can be selected by clicking on it and it would show the dots on the source and destination, along with an x on the middle. The list of words will be obtained by calling a configurable URL. A list will be added to show the list of all connections made, and a button will be added to POST the list of connections to the server.
