	<brief_description>
		A container that represents a basic element that can be placed inside a [GraphEdit] control.
	</brief_description>
	<description>
		[GraphElement] allows to create custom elements for a [GraphEdit] graph. By default such elements can be selected, resized, and repositioned, but they cannot be connected. For a graph element that allows for connections see [GraphNode].
