OpMAP analysis and visualization of large opinion spaces

Publication: Dynamic metaphoric maps

One of the challenges that we faced during the implementation of the OpMap was to produce a map where every country has the size that corresponds to the number of people that hold opinions of that country. Such visualizations constructed starting from geographic maps are well known under the term of cartograms. The OpMap posed two additional challenges to such visualizations:

Since no tool was available to satisfy these needs, we designed and implemented an algorithm that constructs such dynamic metaphoric maps. You can read about it in this paper. This work will be presented during the EuroVIS 2022, June 13-17 in Rome.
