Glyphmaker is a system for data analysis and visualization (Ribarsky, 1993). It is integrated into the SGI Data Explorer to take advantage of the features and flexibility of dataflow visualization systems. Glyphs , which are graphical objects whose elements (e.g. position, size, shape, color, orientation, etc.) are bound to data, are used to design a presentation. This system allows the user to build customized representations of multivariate data. Interactive tools are integrated to explore the patterns in and relations between the data. The main parts of Glyphmaker are the Data Reader, the 3D Glyph Editor and the Glyph Binder. Another important component for the representation is the Conditional Box.
The Data Reader is used to convert input data from a user specified format to the Explorer internal format so that it can be read-in by any existing explorer module.
The Glyph Editor is a simple 3D editor, which is used to draw the glyphs and if desired, to arrange and orient them in compound glyphs.
The Glyph Binder allows interactive bindings or bindings changes between data variables and glyph elements. It also allows one quickly to alter the range of data variables or to alter the range of change in the glyph elements as the data varies from minimum to maximum. Finally the Binder permits the saving of new bindings or reloading of previous ones.
The Conditional Box is a 3D- Box, which can be moved and sized to enclose a subregion of the data after it has been selected for display and bound to particular glyphs, The box allows one to distinguish what is inside from what is outside - in effect to reclassify the data according to this condition.
