/**
 * The SVGElement prototype is a JavaScript wrapper for SVG elements used in the
 * rendering layer of Highcharts. Combined with the
 * {@link Highcharts.SVGRenderer}
 * object, these prototypes allow freeform annotation in the charts or even in
 * HTML pages without instantiating a chart. The SVGElement can also wrap HTML
 * labels, when `text` or `label` elements are created with the `useHTML`
 * parameter.
 *
 * The SVGElement instances are created through factory functions on the
 * {@link Highcharts.SVGRenderer}
 * object, like
 * {@link Highcharts.SVGRenderer#rect|rect},
 * {@link Highcharts.SVGRenderer#path|path},
 * {@link Highcharts.SVGRenderer#text|text},
 * {@link Highcharts.SVGRenderer#label|label},
 * {@link Highcharts.SVGRenderer#g|g}
 * and more.
 *
 * See [How to use the SVG Renderer](
 * https://www.highcharts.com/docs/advanced-chart-features/renderer) for a
 * comprehensive tutorial on how to draw SVG elements on a chart.
