Being able to “read and write” data visualisations is becoming as important as being able to read and write text. Understanding, measuring, and improving data and visualisation literacy is important for understanding STEAM developments and to strategically approach global issues.This session features presentations by researchers and practitioners that develop approaches, tools, and experiences which aim to improve and use the data visualisation literacy of their users. Visualisations of water, global warming, biodiversity, energy, and infectious diseases, health, urban growth and STEAM data will be featured. We will demonstrate how data visualisation can be used to open rich dialogues around crucial issues and serve as a powerful means of making information accessible, salient, and memorable. Discussions will focus on how to best use the power of big data and the continuously evolving set of data mining and visualisation tools to empower the personal and professional decision making by diverse stakeholdersto achieve sustainability.
