Users can then interactively explore and understand these datasets for all sorts of data visualizations, from charts, maps, network diagrams, and even interactive tables. But before we can process or display data in an app, we have to ask, "Where is the data coming from?" Most Shiny apps affect data directly from data files, CSVs, JSON, Excel workbooks, or else the Shiny app accesses data from an external source by an API or database.
