### `autoSize`

Boolean | String

Determines the sizing of the Graphic.

sizeContentToGraphic
  The Graphic's width and height attributes are, either explicitly set through the `width` and `height` attributes or are determined by the dimensions of the parent element. The content contained in the Graphic will be sized to fit with in the Graphic instance's dimensions. When using this setting, the `preserveAspectRatio` attribute will determine how the contents are sized.
sizeGraphicToContent
  (Also accepts a value of true) The Graphic's width and height are determined by the size and positioning of the content.
false
  The Graphic's width and height attributes are, either explicitly set through the `width` and `height` attributes or are determined by the dimensions of the parent element. The contents of the Graphic instance are not affected by this setting.

Default: false

### `contentBounds`

Object readonly

Defined in `graphics/js/SVGGraphic.js:66`

Object containing size and coordinate data for the content of a Graphic in relation to the coordSpace node.

### `height`

Number

Defined in `graphics/js/SVGGraphic.js:115`

Indicates the height of the `Graphic`.

### `id`

String

Defined in `graphics/js/SVGGraphic.js:27`

### `preserveAspectRatio`

String

Defined in `graphics/js/SVGGraphic.js:156`

Determines how content is sized when `autoSize` is set to `sizeContentToGraphic`.

none
  Do not force uniform scaling. Scale the graphic content of the given element non-uniformly if necessary such that the element's bounding box exactly matches the viewport rectangle.
xMinYMin
  Force uniform scaling position along the top left of the Graphic's node.
xMidYMin
  Force uniform scaling horizontally centered and positioned at the top of the Graphic's node.
xMaxYMin
  Force uniform scaling positioned horizontally from the right and vertically from the top.
xMinYMid
Force uniform scaling positioned horizontally from the left and vertically centered.
xMidYMid (the default)
  Force uniform scaling with the content centered.
xMaxYMid
  Force uniform scaling positioned horizontally from the right and vertically centered.
xMinYMax
  Force uniform scaling positioned horizontally from the left and vertically from the bottom.
xMidYMax
  Force uniform scaling horizontally centered and position vertically from the bottom.
xMaxYMax
  Force uniform scaling positioned horizontally from the right and vertically from the bottom.

Default: xMidYMid
