Overall flow chart for the application

In words:
The user starts by inputting their data. There are three options for data input. After the data has been input, we validate that the data is appropriate and interpretable. If not, we send an error message to the user, and ask them to resubmit their data. If the data input is successful, we display the data back to the user and allow the user to include/exclude any populations and/or haplotypes. Following data management, the user is taken to the preview visualization page. Here a google map is displayed showing a visualization of the data. There are various map and view options here that update the page. The user can also return to the data management screen and edit previous choices. Finally, the visualization can be exported in four formats.
