A k-track drawing is a crossing-free 3D straight-line drawing of a graph G on a set of k parallel lines called tracks. The minimum value of k for which G admits a k-track drawing is called the track number of G. In [18] it is proved that every graph from a proper minor closed family has constant track number if and only if it has constant queue number. In this paper we study the track number of...

Clustered graph is a very useful model for drawing large and complex networks. This paper presents a new method for drawing clustered graphs in three dimensions. The method uses a divide and conquer approach. More specifically, it draws each cluster in a 2D plane to minimise occlusion and ease navigation. Then a 3D drawing of the whole graph is constructed by combining these 2D drawings. Our ma...

Artistic drawing is one of the disciplines fine arts; it art embellishing our spaces; a means for artist to express his thoughts and medium he uses provide viewer with reading society. The finds in an indispensable mode expression. Let us specify that “thought”, concept we refer this dissertation, concerns only artist’s intentions, vision world, interpretation social realities. Knowing expressi...
