Group elements, treat them as one

</g>

Element property, transform="…"
Rotation, revolves element around pointtransform="rotate(degrees, cx, cy)"
Scale, multiply all (x,y) coordinatestransform="scale(xfactor, yfactor)"
Translation, add (x,y) positionstransform="translate(dx, dy)"
Transform
Elements declared inside definitions are not rendered. Ideal for reusing elements
