\qmlclass MapCircle
\brief The MapCircle element displays a circle on a map.
\inherits QGeoMapCircleObject
\ingroup qml-location-maps
The circle is specified in terms of a central coordinate and
a radius in metres.
If \l center and \l radius are not specified and valid the
circle will not be displayed.
An example, a MapCircle positioned at your current position (assuming there
is a PositionSource):
\snippet doc/src/snippets/declarative/testpolymapobjects.qml Basic map position marker definition
The element is used with a Map element.
The MapCircle element is part of the \bold{QtMobility.location 1.2} module.
