The image at the beginning of the Lexham Survey of Theology looks fascinating, but it is almost impossible to actually READ because the type gets small and blurry in the lower levels of the "tree." That image should be scalable so the letters are still in vector and crisp and sharp at any size, and there should be a way to zoom in and out so the would-be reader of that tree can actually read it!
Clicking on it opens it in the Media Tool, where it also is un-zoomable and impossible to read the lowest levels of the "tree."
Somebody at Logos worked long and hard to create that information tree, and it's too bad that it is being offered in a format that makes it unusable.
