What I find the most interesting component of DH is precisely this visual mapping of data. I have found these components, whether timeline, mapping, or data mapping in other research I have done in previous classes, and the depth these tools add to any historical analysis is incalculable.
Because my focus is world history, I often end up tackling topics that do not fit neatly into one geographical region or historical event. I often look at movements and trends across huge geographical areas, spanning centuries. These tools of data visualization are enormously helpful in seeing movements of large numbers of people,or for understanding the path of a particular religion or pathogen along trade routes, to name just a few of the possible uses of these tools. It can be one thing to imagine what it must have felt like or looked like to move along these networks, but it is another thing entirely to be able to truly place oneself into history by way of a visual analysis. The depth and nuance that visual analysis of data adds another layer to historical understanding and analysis. For me, this aspect of DH is by far the most intriguing and interesting, and the part of the assemblage of data that I would most want to participate in.
