I chose to do option #2 for this assignment. I googled examples in RStudio Shiny and was lead to this example. The example provided below shows the interactive animation made by someone, to showcase the bus routes in Minneapolis.
In this example, on the right side of the page, you can scroll through the different routes, and only show certain busses (Northbound, Southbound, Eastbound, Westbound). A key on the bottom shows the color of each bus, and where the stops are along the route. When you change the route, as seen in example below, you can see where those buses are located.
Another example I found included a graph done on telephones by region (below).
This example has a menu that will change the entire bar graph, by showcasing different regions. On the right side of the page, you can see what was changed in the coding.
After looking at two of the examples, I can completely see how this would play an essential part in real life. The bus route example could be used in an app on a smartphone, so one would be able to see if the bus will be coming soon. The animation of RStudio Shiny is very intriguing and complex!
