SVG render width

[poiuiopoiu]

My README has an SVG browser badge from Sauce Labs, following the docs. There was no width specified in the tag that inserted the SVG. When the window width is enough to show 2 columns (not the 3-column layout), It looks like the image is being drawn as if the width is 100% window width, so the right part of the SVG actually ends up getting cut off.
