Multivariate Data Visualization and Usability: Preliminary Notes - Modern Trends in Cartography - page 380

order to analyse differences in personal strategies of task completion for both small
multiples and ring maps depiction.
Preliminary results provide stimuli for further investigation of multivariate
methods

effectiveness and efficiency. The proposition that the more unfamiliar
depiction method (ring maps) can be comparable or even more usable than the
commonly used method (small multiples choropleth maps) needs more extensive
research and more robust confirmation. However, these results corroborate the
findings of Kaspar et al. ( 2011 ) that non traditional methods (cartograms in the
case of Kaspar et al. and ring maps in our case) deserve attention and a detailed
analysis of use. Both research directions outlined at the beginning of our study
should be combined in order to find user-friendly and acceptable map design for
particular types of tasks.
