SVG presentation attributes are CSS properties that can be used as attributes on SVG elements.

The <polygon> element defines a closed shape consisting of a set of connected straight line segments. The last point is connected to the first point.

The RegExp object is used for matching text with a pattern.

The amplitude attribute controls the amplitude of the gamma function of a component transfer element when its type attribute is gamma.

The <title> element provides an accessible, short-text description of any SVG container element or graphics element.

The isNaN() function determines whether a value is NaN, first converting the value to a number if necessary. Because coercion inside the isNaN() function can be surprising, you may prefer to use Number.isNaN().

The <marker> element defines a graphic used for drawing arrowheads or polymarkers on a given <path>, <line>, <polyline> or <polygon> element.

The <foreignObject> SVG element includes elements from a different XML namespace. In the context of a browser, it is most likely (X)HTML.

The decodeURI() function decodes a Uniform Resource Identifier (URI) previously created by encodeURI() or a similar routine.

The <font-face-name> element points to a locally installed copy of this font, identified by its name.
