If you need more than one instance for independent SVG objects, you can also use newly created `<svg>` elements.

```js
// returns a window with a document and an svg root node
const window = require('svgdom')
const SVG = require('svg.js')(window)
const document = window.document

// create svg.js instances
const drawA = SVG(document.createElement('svg'))
const drawB = SVG(document.createElement('svg'))
const drawC = SVG(document.createElement('svg'))

// drawA, drawB and drawC are independent svg.js instances you can use as normal
// ...
```

## Fonts

In order to calculate bounding boxes for text the font needs to be loaded first. `svgdom` loads `OpenSans-Regular` by default when no font file for the specified font was found.
