User can specify custom drawFunc, we provide several build-in drawFuncs:

• Label.template.rightText: label will show at node's right, horizontal center aligned.
• Label.template.topText: label will show at node's top, vertical center aligned.

Default drawFunc is rightText.

User can also write customized drawFunc to draw any svg elements, like draw an image:

const element = document.createElementNS('http://www.w3.org/2000/svg', 'image')
element.setAttribute('href', 'http://netv.zjuvag.org/logo.svg')
element.setAttribute('width', '100')
labelManager.draw(node, (node) => { return element })

Update label's position for given node(s).

The label's position will not sync with node when drag or manually change node's position. User may call this function manually.
