#!N  #!Rall182 Graphical User Interface #!N #!EC #!N #!N The graphical 
user interface is built upon the X Window and Motif standards. 
These tools manage multiple application windows that allow a user to 
create and control the visualization process easily and effectively. The graphical 
user interface provides two levels of service. First, non-programmers or users 
with fixed requirements can execute previously created visual programs. These visual 
programs may consist of various menus, dials, sliders, and other interactors 
that provide fixed functions. Second, programmers can create customized visualizations by 
using the interface to interconnect modules in flexible ways, and to 
create new combinations of modules in the form of macros. #!N 
#!N The Data Explorer graphical user interface lets you create or 
work with a visual program to easily realize sample, select, and 
transform data during visualization. You can use the Visual Program Editor 
(VPE) to create new scenarios by simply connecting module icons on 
the screen in any logical sequence. #!N #!N Data Explorer provides 
the following primary windows: #!N #!I0 #!N #!N #!I0 #!N  #!F-adobe-times-bold-r-normal--18*

#!N #!N #!N Data Explorer provides a Colormap Editor window that 
lets you map colors to specified data values and display the 
results in the visual image. The system also provides a Sequencer 
window, which has many uses, including controlling how a sequence of 
images is displayed (with forward and backward direction, repetition, and so 
on). #!N #!N These windows are discussed in detail in  #!Lunduse,dxall274 h Graphical User Interface: Basics  #!EL

 #!F-adobe-times-bold-r-normal--18*   Module Builder: #!EF #!EF #!I50 #!N a point-and-click interface for 
describing the interface to a user-written module. The Module Builder creates 
the necessary makefiles and a template  #!F-adobe-times-bold-r-normal--18*   .c #!EF file for 
the module. (See IBM Visualization Data Explorer Programmer's Reference.) #!I0 #!N
