Is your feature request related to a problem? Please describe.
Currently, once you upload and analyze a document, you have to refresh the application to analyze a new document. This is a request to add a button or link to the form so you can more easily analyze a new document.

Describe the solution you'd like
Add a link to the upper left-hand corner (in the header) to go back to the main form.

Describe alternatives you've considered
display the whole form below the graph
