This workshop provides a brief introduction to various tools and methods used to prepare data for examination digitally. Beginning with the divide between Explanatory and Exploratory Data Analysis, it asks participants to critique several visualizations found in the wild, looking at them with an eye towards understanding the ways they both provide information quickly and succinctly and the ways in which visualizations can be used to hide weaknesses or flaws in the underlying data used. Several tools for visualization will be discussed from the relatively simple to the relatively complex. Participants who want to examine these tools further will have the opportunity to do so during an associated drop-in session, which will occur on January 30th.
