Multi-dimensional data visualization using concentric coordinates
This paper proposes a new method called Concentric Coordinate for
visualizing multidimensional datasets. To reduce the overlapping and edge
crossings among curves, axes are arranged as concentric circles rather than
parallel lines that are commonly used in the traditional approach. Edges which
represent data items are drawn as segments of curves rather than poly-lines
drawn in the classical parallel coordinate approach. Some heuristics are applied
in our new method in order to improve the readability of views. The paper
demonstrates the advantages of new method. In comparison with the parallel
coordinate method, our concentric circle approach can reduce more than 15 %
of the edge overlaps and crossings by visualizing the same dataset. In our new
approach, we further enhance the readability of views by increasing the
crossing angle. Finally, a visual interactive network scans detection system
called CCScanViewer is developed based on our new visualization method to
represent traffic activities in network flows, and the experiments show that the
new approach is effective in detecting unusual patterns of network scans, port
scans, the hidden scans, DDoS attacks etc
