# francy: Interactive Discrete Mathematics in GAP
#
#! @Chapter Francy Renderers
#! <C>FrancyRenderer</C> is an object that holds the renderer name to be used by the client to display the graphics.
#! <P/>
#! Francy JS allows users to switch between renderers in runtime, but if the renderer is specified in the GAP code,
#! then the user won't be able to switch between renderers on the client side.
#! <P/>
#! This implementation knows only about the official supported renderers: <C>D3</C>, <C>Vis</C> and <C>Graphviz</C>.
#! Please see Francy-JS for client implementation.
#! @Section Categories
#! In this section we show all Francy FrancyRenderer Categories.
#! @Description
#! Identifies <C>FrancyRenderer</C> objects.

#! Examples:
#! <P/>
#! Configure <C>FrancyRendererType.VIS</C> as the renderer for a specific canvas:
#! @InsertChunk Example_Create_Renderer_1
#! <P/>
#! @Arguments IsFrancyRendererType
#! @Returns <C>FrancyRenderer</C>
DeclareOperation("FrancyRenderer", [IsFrancyRendererType]);
#! @Section Global
#! In this section we show all Global FrancyRendererType records for multi purpose.
#! @Description
#! The various types of <C>FrancyRendererType</C> supported.
#! @Returns <C>rec</C> of <C>FrancyRendererType</C>
