+- SVG images should be scalable as they will be rendered in a variety
+ of places (web, PDF, etc.) as well as in different viewports
+ (desktop, mobile, etc.). To help the images successfully scale,
+ employ a "viewBox" attribute in the SVG tag. For example,
+ to create an image with a default width and height of 400x300,
+ you would use viewBox="0.00 0.00 400.00 300.00"
