Anchors” (DAs). For each of d dimensions there is a corresponding DA.
An instance of RadViz is shown in Fig. 13.1.
Fig. 13.6. A RadViz image of a 14d data set
Fig. 13.7. An illustration of RadViz's spring force analogy. The point connected to
the DAs on the boundary of the circle is (6.4, 2.2, 1.1, 3.2, 2.3, 2.8) and its position
determined where the sum of the forces (determined by each coordinate) is 0.
Data records are mapped to locations within the unit circle using a
transformation based on Hooke's Law and what is commonly referred to
