BoundingBox is set of two Types/Position. BoundingBoxes are typically centered around the position of an entity.
In Factorio, the coordinate system is in a "programming" orientation, left-to-right, top-to-bottom. The upper-left point is the least dimension in x and y, and lower-right is the greatest.
It is specified like this:
{{-0.4, -0.4}, {0.4, 0.4}}
The first position is assumed to be leftTop, the second position is assumed to be rightBottom. A third member may be added, a Types/float that represents the orientation, however it does not seem to be used.
The less commonly seen, but expanded form:
{
left_top = {-0.4, -0.4},
right_bottom = {0.4, 0.4}
}
