[wilke0818]

In order to better help users interact with our map, we will want to include a dropdown menu that will allow for the user to change which overlay they are seeing. We will also want a transparency slider that can make the borders of countries more transparent and better show the characteristic regions.

• Create a slider that will allow us to make the political boundaries more transparent (work with the democracy visualization group to reuse theirs)
• Create a dropdown menu to select between different overlay datasets Create reusable dropdown component #54
