Orthogonal and Smooth Orthogonal Layouts of 1-Planar Graphs with Low Edge Complexity
Evmorfia Argyriou, Sabine Cornelsen, Henry Förster +5
While orthogonal drawings have a long history, smooth orthogonal drawings have been introduced only recently. So far, only planar drawings or drawings with an arbitrary number of c…
A Fraud Detection Visualization System Utilizing Radial Drawings and Heat-maps
Evmorfia N. Argyriou, Antonios Symvonis, Vassilis Vassiliou
We present a prototype system developed in cooperation with a business organization that combines information visualization and pattern-matching techniques to detect fraudulent act…
Occupational Fraud Detection Through Visualization
Evmorfia N. Argyriou, Aikaterini A. Sotiraki, Antonios Symvonis
Occupational fraud affects many companies worldwide causing them economic loss and liability issues towards their customers and other involved entities. Detecting internal fraud in…
Geometric Simultaneous RAC Drawings of Graphs
Evmorfia N. Argyriou, Michael A. Bekos, Michael Kaufmann +1
In this paper, we introduce and study "geometric simultaneous RAC drawing problems", i.e., a combination of problems on geometric RAC drawings and geometric simultaneous graph draw…
The Straight-Line RAC Drawing Problem is NP-Hard
Evmorfia N. Argyriou, Michael A. Bekos, Antonios Symvonis
Recent cognitive experiments have shown that the negative impact of an edge crossing on the human understanding of a graph drawing, tends to be eliminated in the case where the cro…
Maximizing the Total Resolution of Graphs
Evmorfia N. Argyriou, Michael A. Bekos, Antonios Symvonis
A major factor affecting the readability of a graph drawing is its resolution. In the graph drawing literature, the resolution of a drawing is either measured based on the angles f…
