From Wikipedia:

Yoix technology provides a pure Java programming language implementation of a general purpose dynamic programming language developed by researchers at AT&T Labs. Its syntax and grammar should be easy to learn for those familiar with the C programming language and Java. To an end-user, a Yoix application is indistinguishable from a Java application, but to the application developer Yoix should provide a simpler coding experience than working in Java directly, much like writing Perl code can be simpler than writing C code. ... The Yoix language is not an object oriented language, but makes use of over 165 object types that provide access to most of the standard Java classes. Because the Yoix interpreter is built entirely using Java technology, it means that Yoix applications are cross-platform, GUI-capable and both network and thread friendly, yet Yoix developers find themselves insulated from the more complex and error-prone parts of coding the same functionality directly in Java. It does not use reflection to access Java functionality and thus adds value by not only simplifying access to that functionality, but also improving application reliability by coding through both Java glitches and complicated Java features one-time, behind-the-scenes. The Yoix language includes safe pointers, addressing, declarations, and global and local variables. In addition to supporting native user functions, users can add their own builtin functions written in Java. The two central elements in the Yoix design are borrowed from the PostScript language: dictionaries as language components and permissions-protected dictionaries as exposed system components. Homage to the Tcl language and its exposure philosophy should also be given, though it did not have a direct influence. ... Another key Yoix design element involves pointers and addressing. Pointers and pointer arithmetic in the Yoix language is syntactically similar to what is found in the C language, but the Yoix implementation prevents using a pointer outside its bounds. In addition, the address operator always produces a valid, usable result.

In addition to its role as a tool for building GUI applications, Yoix technology supports several modes of data visualization. Data mining A data visualization module called YDAT (Yoix Data Analysis Tool) has been included in the public Yoix distribution since release 2.1.2. YDAT uses a data manager component to coordinate data display and filtering among its several visualization components that include an event plot, a graph drawing pane, histogram filters and tabular detail. YDAT is able to display graphs generated by the GraphViz graph drawing and layout tool, which is another open source tool freely available from AT&T Labs. YDAT is highly configurable at the Yoix language level. The image below is a screenshot of a Yoix YDAT instantiation, which in this example is being used to analyze vehicle auction transactions. Graph drawing Yoix technology provides good support for graph drawing. In addition to graph display mentioned above as part of the YDAT module, data types in the Yoix language support building, manipulating and traversing graph structures. Native Yoix functions support the DOT language output and a built-in DOT language parser to facilitate interaction with the GraphViz layout engines. ** Organizing cells of data** The YChart data visualization toolkit was added to the Yoix distribution with release 2.2.0. YChart allows one to organize and display cells of data. Two interactive YChart applications contained in the Yoix distribution are a Periodic Table of the Elements and a Unicode Chart. A program to demonstrate using YChart with variable width cells, as might occur with a schedule, is also available in the Yoix distribution. Interactive 2D graphics The Yoix distribution also includes a Yoix package, called Byzgraf, for rendering basic data plots such as line charts, histograms and statistical box plots.
