The most arresting part of the screen saver is a colorful, animated 3-D graph
. It displays your assigned work unit as a horizontal grid of radio hiss about 10 kilohertz wide by 107 seconds deep.
Creating 2-D and 3-D animations is easy; even middle school students can explore what makes a 3-D graph
shrink and grow, or what values make it move up and down.
Users can now view rotatable OpenGL 3-D graphs
, which can be distributed and used without installing the analysis and graphing software.
Users now can rotate, pan, and zoom within 3-D graphs
to examine details more efficiently than in previous versions.
Using relatively realistic 3-D graphs
with several elements, Siegrist (1996) failed to support Tufte's hypothesis that charts with a high data-ink ratio should be superior to those with a low data-ink ratio.
