defs

The defs element is used to store graphical objects that will be used at a later time. Objects created inside a defs element are not rendered directly. To display them you have to reference them (with a use element for example).

Usually, this element is created with:

const defs = parentElement.add('defs')

It's possible to create it as a disconnected element with gySVG('defs') and attach it to the SVG document with .attachTo().
