I'm not sure how to answer you helpfully because there seem to be a few
misconceptions here. To start with, the edge properties are not the
edges themselves; they're just associated properties. Secondly, the
graph you've declared doesn't specify any bundled edge properties; it
specifies bbox as a bundled vertex property.
...but the straightforward answer to your question is that the first two
parameters to add_edge should be vertex descriptors, usually as obtained
from the add_vertex function.
