In continuation of a previous work, where a geometrical interpretation of intuitionistic fuzzy sets was given in the form of a radar chart, here it is proposed the geometrical interpretation of their extension, called interval-valued intuitionistic fuzzy sets. Radar charts, which are useful for representing multivariate data sets, and especially for data from time series. The idea is illustrated by an example with real meteorological data.
