The <title> element provides an accessible, short-text description of any SVG container element or graphics element.
Text in a <title> element is not rendered as part of the graphic, but browsers usually display it as a tooltip. If an element can be described by visible text, it is recommended to reference that text with an aria-labelledby attribute rather than using the <title> element.
Note: For backward compatibility with SVG 1.1, <title> elements should be the first child element of their parent.
