Abstract
The popularity and availability of digital tools has boosted the use of thematic maps in infographics and data visualizations. Unlike general purpose maps, thematic maps are aimed at communicating the spatial distribution of a particular topic or theme, such as population density, voter preference or income. Since thematic maps have been more often studied and tailored for European and North American countries, some of them need adjustment to properly represent Brazilian states, according to their needs. The aim of this paper is to present the hexagonal hierarchical cartogram, which represents Brazilian states in a normalized geographical format using single-hue color scales to show magnitude. We demonstrate its use by mapping average grades obtained by students of all Brazilian states in a national exam called ENEM (Exame Nacional do Ensino Medio).

A thematic map for Brazilian states, in particular, presents interesting challenges, since the states are strongly diverse in area, economic
In order to evaluate the special needs for a thematic map of Brazil by state in face of its geographic peculiarities, this paper focuses on a case study that maps ENEM average grades by exam type to each Brazilian state
Summary
Maps are abstractions of a three-dimensional world depicted on the bidimensional surface of a sheet of paper or a video screen. Considering that most thematic maps have been created and researched more often in European and North American countries, it is reasonable to assume that these types of maps have been designed according to requirements and needs of these countries. This hypothesis could be investigated by, say, conducting a large survey of examples from many years, a more practical approach was chosen, namely, designing a thematic map of Brazil suitable to present data pertaining to Brazilian states.
