annotation

data-foo="123"

The literal values of attributes prefixed with data- are assigned on the annotation’s scope. Attribute dashes are converted to camel case (i.e., data-foo-bar="11" puts fooBar: 11 on the scope).

map-xy="xDim yDim"

The x and y dimensions of the data which should be used to position the annotation, separated by whitespace. If this aesthetic is used, both scaleX and scaleY must be in scope.

map-position="dimension"

The dimension of the data which should be used to position the annotation. If this aesthetic is used, one of scaleX or scaleY must be in scope, but not both.
