They are for ZOOMING in and out of the TREE and the four ARROWS are for Navigating.
The TREE in MENU can only be viewed with certain Providers as it is a Tribal Pages BETA.
I cannot see it with IE but I can with CHROME,

The reason I could not find TREE as your example is that each Internet Provider shows it differently, and as I use Internet Explorer, it did not show correctly, so I switched to Chrome and I found it, as it is a BETA of Tribal Pages who are testing it.
If you look closely the PLUS CIRCLE is showing the BLOOD LINE of the person you select, and Selecting it shows the MENU Edit and Additions you can make.
The Blank Circle if you click on it takes you to a Menu to select that Person to show thir tree plus some EDIT
You will also See TEXT Family and Tree in box, These are Similar to Circles for Selection
