- _cssClass: node css class name
- _labelClass: node label css class name
- svgSym: node icon, svg document (only works in svg renderer)
- _size : node size (svg renderer only)
- _width: node width (svg renderer only)
- _height: node height (svg renderer only)
- _svgAttrs: Object, svg node attributes
Link Object
- id: link id. If not provided uses array index
- name: node name. If not provided uses: 'link [link_id]'
- tid: id of target node
- sid: id of source node

Css style and canvas style
SVG css classes:
- .node: nodes symbol
- .link: link line
- .node-label: nodes names
- .node .selected: node selected
- .link .selected link selected
- .node .pinned: node pinned
To use this css styles in canvas we create 'ghosts' svg elements to pick up values from computed css properties.
If you want, you can stylize the canvas elements directly, setting: options.canvasStyles, but these styles will not be applied to the svg graph.
see: src/canvasStyles.js
