[Geojs-users] Programatically creating annotations

[David Manthey]

If layer is an annotationLayer, then you can create a point like so:

layer.addAnnotation(geo.annotation.pointAnnotation({position: {x:
-118, y: 37}}))

Each annotation takes separate options. They all take an optional style
specification. Points get a single position. Polygons take a list of
vertices (alternately called coordinates). Rectangles take a list of corners
(alternately called coordinates).
