  Urgency of application and development of cognitive graphic tools for usage
in intelligent systems of data analysis, decision making and its justifications
is given. Cognitive graphic tool "2-simplex prism" and examples of its usage
are presented. Specificity of program realization of cognitive graphics tools
invariant to problem areas is described. Most significant results are given and
discussed. Future investigations are connected with usage of new approach to
rendering, cross-platform realization, cognitive features improving and
expanding of n-simplex family.
