+"""
+This example shows how to insert text into a scene using TextItem. This class 
+is for displaying text that is anchored to a particular location in the data
+coordinate system, but which is always displayed unscaled. 
+
+For text that scales with the data, use QTextItem. 
+For text that can be placed in a layout, use LabelItem.
