Methods

Annotations.prototype.render()

Renders an instance as a Virtual DOM tree.

var node = new Annotations();

var vtree = node.render();
/* e.g., returns
    {
        'tagName': 'g',
        'properties': {
            'property': 'annotations',
            'className': 'annotations',
            'attributes': {
                'transform': 'translate(0,0)'
            },
            'namespace': void 0
        },
        'children': [],
        'namespace': 'http://www.w3.org/2000/svg',
        'count': 0,
        'hasWidgets': false,
        'hasThunks': false,

        'key': void 0
    }

Events

'render'

Event emitted when an instance renders. The event object is the rendered Virtual DOM tree.

var node = new Annotations();

function onRender( vtree ) {
    console.log( vtree );
}

node.on( 'render', onRender );
node.render();

---

Listeners

'change'

Upon receiving a 'change' event, an instance re-renders.

var node = new Annotations();

function onRender( vtree ) {
    console.log( vtree );
}

node.on( 'render', onRender );
node.emit( 'change' );

Examples

var toHTML = require( 'vdom-to-html' );
var annotations = require( '@stdlib/plot/components/svg/annotations' );

// Create a new component:
var node = annotations();

// Render as a virtual DOM tree:
var vtree = node.render();

// Transform the virtual DOM tree to HTML:
var html = toHTML( vtree );
// returns <g property="annotations" class="annotations" transform="translate(0,0)"></g>
