svg
The <svg> component is a basic container. It can be used as the root node of an SVG document or be used to nest an SVG fragment into an SVG document.
NOTE - This component is supported since API version 7. Updates will be marked with a superscript to indicate their earliest API version.
- The width and height must be defined for the <svg> parent component or <svg> component. Otherwise, the component is not drawn.
