An example of a drawing algorithm is given in Section Techniques First, we define some terminology on graphs pertinent to graph drawing. Through- . display of symmetries are highly desirable in visualization applications. Also, it is.

Graph drawing is an area of mathematics and computer science combining methods from geometric graph theory and information visualization to derive two-dimensional depictions of graphs arising from applications such as social network analysis , cartography , linguistics , and bioinformatics. A drawing of a graph or network diagram is a pictorial representation of the vertices and edges of a graph. This drawing should not be confused with the graph itself: In the concrete, however, the arrangement of these vertices and edges within a drawing affects its understandability, usability, fabrication cost, and aesthetics. Graphs are frequently drawn as node—link diagrams in which the vertices are represented as disks, boxes, or textual labels and the edges are represented as line segments , polylines , or curves in the Euclidean plane. In the case of directed graphs , arrowheads form a commonly used graphical convention to show their orientation ; [2] however, user studies have shown that other conventions such as tapering provide this information more effectively.

In the case of directed graphs , arrowheads form a commonly used graphical convention to show their orientation ; [2] however, user studies have shown that other conventions such as tapering provide this information more effectively. Alternative conventions to node—link diagrams include adjacency representations such as circle packings , in which vertices are represented by disjoint regions in the plane and edges are represented by adjacencies between regions; intersection representations in which vertices are represented by non-disjoint geometric objects and edges are represented by their intersections; visibility representations in which vertices are represented by regions in the plane and edges are represented by regions that have an unobstructed line of sight to each other; confluent drawings, in which edges are represented as smooth curves within mathematical train tracks ; fabrics, in which nodes are represented as horizontal lines and edges as vertical lines; [8] and visualizations of the adjacency matrix of the graph.

Many different quality measures have been defined for graph drawings, in an attempt to find objective means of evaluating their aesthetics and usability. In addition, the placement and routing steps of electronic design automation EDA are similar in many ways to graph drawing, as is the problem of greedy embedding in distributed computing , and the graph drawing literature includes several results borrowed from the EDA literature.

However, these problems also differ in several important ways: From Wikipedia, the free encyclopedia. This article is about the general subject of graph drawing. For the annual research symposium, see International Symposium on Graph Drawing.
