 """An interface for publishing rich data to frontends.
 
 There are two components of the display system:
 
 * Display formatters, which take a Python object and compute the
-  representation of the object in various formats (text, HTML, SVg, etc.).
+  representation of the object in various formats (text, HTML, SVG, etc.).
 * The display publisher that is used to send the representation data to the
   various frontends.
 
 This module defines the logic display publishing. The display publisher uses
 the ``display_data`` message type that is defined in the IPython messaging
 spec.
