The <set> SVG element provides a method of setting the value of an attribute for a specified duration.

The calcMode attribute specifies the interpolation mode for the animation.

The <tspan> SVG element defines a subtext within a <text> element or another <tspan> element. It allows for adjustment of the style and/or position of that subtext as needed.

The color-interpolation-filters attribute specifies the color space for imaging operations performed via filter effects.

The super keyword is used to access properties on an object literal or class's [[Prototype]], or invoke a superclass's constructor.

The accumulate attribute controls whether or not an animation is cumulative.

The <symbol> SVG element is used to define graphical template objects which can be instantiated by a <use> element.

The <textPath> SVG element is used to render text along the shape of a <path> element. The text must be enclosed in the <textPath> element and its href attribute is used to reference the desired <path>.

The Float32Array typed array represents an array of 32-bit floating point numbers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0 unless initialization data is explicitly provided. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

The ascent attribute defines the maximum unaccented height of the font within the font coordinate system.
