Some references to help you get started.
All you'd need to build a basic line chart is, Encounter Date (dimension) in columns shelf and Encounters (Measures) in Rows shelf. In "Show Me" select line graph.
For further reading on what you can do in Tableau this is a great place to start.

Thank you for the reply and the link. I'm wondering how I can create a multi-series chart from the data I have.
Thank you! That is exactly what I need. How did you go about it? Did you pivot the data?
Yes, I pivoted your data and created a dual axis and then added vertical reference line. Just Reverse Engineer it.
