RadViz and Data Understanding
Original language description
The paper searches for those properties of RadViz visualization method [4] mapping data from n dimensional space into a plane which are important for identification of clusters in the original multidimensional data. There are identified two observations(see the Sections 3 and 6) which help to specify clear conditions under which "real" clusters appear even in the RadViz image. The key idea is illustrated using 2 characteristic examples of datasets pointing to a certain drawback of the original RadVizmapping. The identified problem can be resolved using 2 minor modifications of the RadViz algorithm which are suggested in the last section of this contribution. Finally we suggest an algorithm for search of attributes relevant for clustering the studied data.

RadViz a porozumění datům
Czech description
Vizualizační metoda RadViz mapuje data z n-dimenzionálního prostoru do roviny. Dvě velmi jednoduché modifikace algoritmu RadVizu umožňují, že je možné využít tuto vizualizační metodu i pro identifikaci shluků v původních datech. Základní myšlenka metodyje ilustrována na dvou příkladech, které jsou zobrazeny jak v klasickém 3D grafu tak pomocí metody RadViz.
