I'm working on an RStudio program right now to display air routes from one city to another in a 3D fashion. This is part of my graduate work for Harvard DCE's "Classic Mathematics with a Modern User Interface" course.
I will update this post with a link to the shiny program once I've completed it.
I've completed the app.Click here to view it.
I'm unsure of how long I will leave this published due to Shiny connect costing money after 5 free projects. I will need to keep as many free projects available as I can.
