Display X,Y coordinations on SVG map

Oh boy.  Looks like there is a hard limit on the image size in table and matrix visuals - 150px height.

You would need to redo your SVG to take that into account and reduce the whitespace around the drawing.  Or someone can com up with a way to break out of the 150 px limit.

here's my current svg version. Note: replace ":"  with ":"

 </svg>"

which still results in lots of wasted space

You want your SVG to be square (for example 600x600) and with little space around the drawing.
