svgz, almost certainly gzip compressed svg
https://en.wikipedia.org/wiki/Scalable_Vector_Graphics
svg is scalable vector graphics and is all the rave now days, in part
because unlike bitmaps (aka raster-graphics), vector-graphics naturally
scales to different resolutions because it's not pixel-specific but
rather vectors (more or less, draw a line from N percentage from the left
edge and M percentage from the top edge, at A angle, L percentage length).
svg is stored in XML format and thus is (to a limited extent) plain-text-
editor editable, as long as you're careful not to destroy the XML
formatting. But larger scale image composition and editing is typically
done with a vector graphics editor. Inkscape is the most widely known
freedomware vector graphics editor.
Being xml-text-based, svgs generally compress quite well, and the z
extension suffix indicates this one is gzip-compressed.
So for light tweaking, you should be able to make a backup copy of the
file just in case, then gunzip your working copy, edit it in your
favorite text editor, save, and gzip it back up. Of course if you have
inkscape or the like already installed, you can use it, but I'm guessing
if you did you'd know about svg, so you probably don't. And for a quick
tweak, the text editor will likely work just as well, without the hassle
of having to do a whole big inkscape install just for a trivial edit.
