The real value here is that representations of your data can be manipulated on the fly by your users. We do our best to get into our users heads and present the data in a clean simple way, but there can be too much to simplify yet still have meaning; there is a constant balance between depth and breadth. If you can rearrange the position of different charts you address peoples' ability to absorb the information quickly, and if people can replace plots with new ones, based on your estimation of what's potentially interesting, they can customize their view. Now your Shiny app is a plug and play system designed to give users flexibility based on their interests.
