Hi Ruud
No sorry I just tried this made no difference in the browser the image
just displays the actual image I want but if I open in inkscape I can
see all the interconnecting roads outside of the viewable box. We need
to do a clean crop where by all that is placed inside the viewbox is all
that is added to the svg not anything else as it is making the file to
big.
Thanks :)
