Real coding

Letting away all the redundancies (2692 bytes), the remaining active code would be (420 bytes)

Simplification

The viewBox-transformation is of no advantage at all, it just conceals the used values.
Without viewBoxing and with a precision more than reasonable it would be (250 bytes)

<?xml version="1.0" encoding="UTF-8"?>
