3 | ## perspective-viewer
|
4 | Module for the `<perspective-viewer>` custom element.
This module has no exports, but importing it has a side
effect: the [module:perspective_viewer~PerspectiveViewer](module:perspective_viewer~PerspectiveViewer) class is
registered as a custom element, after which it can be used as a standard DOM
element.
The documentation in this module defines the instance structure of a
`<perspective-viewer>` DOM object instantiated typically, through HTML or any
relevent DOM method e.g. `document.createElement("perspective-viewer")` or
`document.getElementsByTagName("perspective-viewer")`.

82 | #### new PerspectiveViewer()
|
83 | The HTMLElement class for `<perspective-viewer>` custom element.
This class is not exported, so this constructor cannot be invoked in the
typical manner; instead, instances of the class are created through the
Custom Elements DOM API.
Properties of an instance of this class, such as
[module:perspective_viewer~PerspectiveViewer#columns](module:perspective_viewer~PerspectiveViewer#columns), are reflected on
the DOM element as Attributes, and should be accessed as such - e.g.
`instance.setAttribute("columns", JSON.stringify(["a", "b"]))`.
|
84 |
|
85 | **Example**
|
86 | ```js
|
87 | // Create a new `<perspective-viewer>`
const elem = document.createElement("perspective-viewer");
elem.setAttribute("columns", JSON.stringify(["a", "b"]));
document.body.appendChild(elem);
