This article arises from the interest to gather and expand the discussions and reflections embraced in lectures on the subject data visualization in the eighth edition of Campus Party Brazil, an event attended by the authors of this text both in its organization as in the communication of content. Thus, this paper aims, initially, to make a terminological and conceptual review of data visualization. Then, it evidences and deepens some emerging topics highlighted by Brazilian researchers in their lectures such as: visualization in physical interfaces, collaborative mapping, storytelling in journalistic infographics, environmental information systems, interdisciplinary teaching and practice of data visualization and understanding of economic data through visual schemes.

CARTOGRAPHIC INTERFACES
Three innovative features:
1. multidimensionality – the ability to add n informative layers in
the same map and relate them;
2. sensors - enables the collection of physical data automatically
through interconnected devices (that characterize the
phenomenon Internet of Things) and the mapping in cartographic
interfaces;
3. collaboration* - a co-working, multidirectional and decentralized
framework which leads to a a non-hierarchical work relationship.
