Abstract: In this paper, we present the idea of visualization of fuzzy and intuitionistic fuzzy data by radar charts, which are useful for representing multivaried data sets, and especially for data from time series. Comparison is given between the run charts and radar charts, as well as between the applications of radar charts in fuzzy and in intuitionistic fuzzy data sets. The graphical presentation of fuzzy data by radar charts seems to be very obvious and natural, while the same done for intuitionistic fuzzy data, as distinguished from the fuzzy data by the addition of second component of set non-membership, seems to bring innovation not only to the field of intuitionistic fuzzy sets, but also to the representational technique of radar charts.
