A graph is a set of nodes and edges where the nodes are objects & the edges the connections between these objects. These can be used to describe diagrams, networks, hierarchies, data flow diagrams, data structures and more. Quite a few packages are available for performing various tasks relating to graphics. These packages include those for creating and manipulating graphics & images, for building 2- & 3-D models for ray tracing, for volume visualization and for converting between various graphics formats. They range from standalone programs to collections of tools to libraries, toolkits for implementing graph editors & graph drawing algorithms. Graphlet is a graph editor, a toolkit for graph editors, a programming language for graphs and a toolkit for graph drawing algorithms. The graph editor toolkit is a powerful toolkit for graph editors & is implemented in C++, LEDA, Tcl/Tk and Graphscript. Graphscript is a high level scripting language based on Tcl/TK with which users can customize and extend graph editors. Graph drawing algorithms help turn abstract graph structures into nicely arranged sets of nodes and edges.
