His final takeaways for visualizing data: The most important thing is to start by knowing what question you want to ask. Then find the appropriate form to represent and/or answer your question. Keep in mind that the entire enterprise of your data and software is rooted in a context, form, and ideology. But that said, with data visualization you can learn some really cool stuff.
With all of these tools, resources, and examples, the workshop repeatedly returned to pedagogical applications. For example, we explored representations of keywords in presidents’ State of the Union Addresses from various points through US History. These keywords were visualized in an optometrist’s list, with the most frequently appearing words located in the “E” spot. We agreed that these posters would be useful tools to generate discussion about changing trends through American history — for example, what does it tell us that Lincoln’s most prominent word was “Emancipation” and George W. Bush’s was “Terror”?
It’s just one example, but really there are countless applications of data visualization for the classroom.
