This example demonstrates a map containing an interactive route and
three VectorMarkers containing separate hover and click popups. Unlike
the ALKMaps.Layer.Markers layer, the
ALKMaps.Layer.VectorMarkers layer in combination with the
ALKMaps.Control.FeatureEvent control is capable of having
interactive popups without affecting the interactive routing
functionality. This example also demonstrates the three different ways
of styling a VectorMarker.
