.... HP s Softbench, and SGI s CodeVision, in visual approaches to reengineering such as the Rigi system [16] in data structure display [17] and in abstract displays such as Seesoft [5] or execution murals [9] The various efforts at algorithm animation represent a second approach to this problem [2,3,12,25,32]. These approaches are generally useful for small scale examples, but do not scale up. FIGURE 1. Defining the information to visualize. Another category of software visualizations deal with understanding performance. These include displays for sequential programs such as that provided by Purify ....

....that the visualizer must know very well the code, but, at the same time, it allows to customize the visualization according to the effective necessities of the user. The two most recent works that make use of ZEUS introduce the use of color and sound [3] and add the three dimensional extension [4], respectively. UWPI [7] automatically provides visualizations for the high level abstract data structures designed by the programmer. To this aim, its heart is an inferencer which analyzes each of the data structures in the source code and suggests a number of plausible abstractions for ....

....Algorithm Animation works at a higher level than code or program visualization, and abstracts the essential operations in order to show how an algorithm works. Examples of systems are Balsa [BRO85b] Tango [STA90] and Zeus [BRO91] which show animations in two dimensions, and the one described in [BRO93] which animate in three dimensions. Brown [BRO88] claims that automatic algorithmic animations are not possible. The operations in source code may not correspond to the operations in an algorithm the swap operator may be implemented as three assignments, and so the algorithmic operations can ....

....colour than to give to a distinct shape. Therefore, more objects can be displayed on the screen; highlighting activity; by painting corresponding features in different views with the same colour, these views can be united; emphasising patterns; making history visible. Brown and Norjak [BRO93] give a number of suggestions for the use of 3D also in algorithm animation: 1 Author s choice of word, not mine 22 . Expressing fundamental information about structures that are inherently 2D, for example a two dimensional matrix could be viewed as an array of sticks with height proportional ....

....class browser, all of which were designed to handle moderately large software systems and which were present in our previous environment FIELD [15] and are now standard in many programming environments. Other visualizations show data structures either statically [12] or through algorithm animation [2,3,8,23], show performance information [1,7,11,22] or show other aspects of the program as the heap visualizer in FIELD or the various views of Seesoft [5] Program visualization is also related to the more general field of information visualization and data mining.

....work looks at dynamic visualization of object oriented programs [10] This work uses a 2D visualization similar to our TimeMaps but provides compression techniques to allow browsing at different levels of detail. The various efforts at algorithm animation are a second approach to this problem [3,4,12,24,31]. Here the implementor crafts detailed displays that describe the underlying behavior of a specific program and its data. These systems generally let the user customize the display (with varying degrees of difficulty) and tie the display to the underlying algorithm. For example, Balsa and Tango ....
