Produce a lot of white space below the diagram: Interestingly enough, the empty white space depends on how wide the diagram fans out. For instance here is the same but with short names and the resulting smaller useless whitespace:

Here is the markdown producing the above result with lot's of whitespace:

Mark down causing the white space. Please note, I put a pound sign before the two inner ``` code boxes, so that it displays correctly in github.
