This example demonstrates the capability to plot paths on the map and manipulate them.
Click anywhere on the map to place a node and continue clicking to create new nodes. A border will be drawn sequentially
connecting the nodes. You can click on the nodes or drag them to manipulate the border. Clicking on a line in between nodes
will insert another node in between the two surrounding nodes.
Use the array of controls below to modify the border's appearance and behavior, or to import/export KML data.
