Effective visual communication
What is EVC?
Effective visual communication is a core competency for pharmacometricians, statisticians, and more generally any quantitative scientist. It is essential in every step of a quantitative workflow, from scoping to execution and communicating results and conclusions. With this competency, we can better understand data and influence decisions towards appropriate actions. Without it, we can fool ourselves and others and pave the way to wrong conclusions and actions. The goal of this tutorial is to convey this competency.
The three laws
We posit three laws of effective visual communication for the quantitative scientist:
- have a clear purpose,
- show the data clearly,
- and make the message obvious.
Cheat sheet and hands-on tutorial
We defined the three laws of effective visual communication to provide overarching principled advice that can serve as a guiding star towards effective visual communication for the quantitative scientist. A concise Cheat Sheet, distills more granular recommendations for everyday practical use. Finally, these laws and recommendations are illustrated in four case studies. The aim of this site is to provide both the code, data and examples as stand alone posts. We hope that it proves useful for putting the three laws into practice.
To further ease implementation in practice, it helps to distill the three laws in to even more detailed recommendations and illustrate them concretely. This is why we introduced a cheat Sheet. This single-page reference sheet is an integral part of this tutorial, carefully designed as a concise and accessible resource for everyday practical use. Yet, it draws from a wide range of sources including (Bonate 2014; Jean L. Doumont 2002; Cairo 2016; Few 2012; Ware 2004; B. Wong 2010, 2011; J. L. Doumont 2009; Heer and Bostock 2010; Tufte 1986, 1997; Gelman and Unwin 2013; D. M. Wong 2010; Wainer 1984; Munzner 2015; Cleveland 1985; Cleveland and McGill 1985, 1987; Wilkinson 2005; Tukey 1977; Duke et al. 2015; Robbins 2012).
