The coins can be arranged into various layouts such as piles representing, for example, metal types, or streams visualizing the ebb and flow of coins over the centuries.
This concept of visualizing data as "streams visualizing the ebb and flow of coins over the centuries" is highly relevant to my research. I need to show change over time, specifically the sudden drop in coins or shift in material (like the debasement of currency) that occurs during and immediately after the plague years (1347-1351). This idea of "dynamic streams" helps me think past a static map and towards visualizing economic instability and recovery across Europe.
