the Visual Statistics System,
statistical visualizations that are
highly dynamic and very interactive.
High-Interaction, Multi-View Graphics:
constructs very-high-interaction, dynamic graphics
that show you multiple views of your data simultaneously.
The graphics are designed to augment your visual
intuition so that you can better understand your
What Your Data Have To Say: ViSta's visually
intuitive and computationally intensive approach
to statistical data analysis is designed to clarify
the meaning of data so that you can see
what your data have to say.
ViSta is available in English, Français,

dynamic, interactive plots that show you what
your data or analysis seems to say
that guide your analysis

Capabilities: ViSta performs Univariate
and Multivariate Statistical
Visualization and Data Analysis.
Plugins, Scripts and DataPrograms:
Teachers can develop ViSta Web Applets for
demonstrations, examples, test problems, etc.
Students can download and run these on their
own machines (example
of class notes using an applet).
Teachers can write ViSta scripts using the same
techniques as for Applets, but keep them privately
on their machines. A grading script is an example.
Teachers and students can write dataprograms
to manipulate their data.
Programmers can develop plugins to add entirely
new data analysis and visualization capabilities.
Tools: ViSta provides access to the underlying
development languages, including:
ViSta's Data Analysis Language for writing applets,
scripts and data programs; and
an object-oriented programming language which
can be used to write ViSta plugins for statistical
computing and dynamic graphics.
a free and open Lisp system satisfying most
of the Common Lisp standards.
and FORTRAN may be used for developing specialized
addition, ViSta has developers tools including
a byte-code compiler, a stepper, tracing and back
tracing, object and bitmap editors, distribution
