# 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.
