  • h: Number

• offset: Object, graph center offset

  • x: Number
  • y: Number

• linkWidth: Number, link thickness in px
• nodeLabels: Boolean, show nodes names
• linkLabels: Boolean, show links names
• fontSize: Number, for node labels, px
• strLinks: Boolean, draw links as rect lines
• resizeListener:Boolean, defaults: true ,add listener to window.resize event
• noNodes: Boolean, no render nodes

Events

• node-click: fired when click on node, emits (event,node-object)
• node-hover: fired when mouseover on node, emits (event, node-object)
• link-click: fired when click on link, emits (event, link-object)
• screen-shot: fired when screenshot creation is done, emits (error)

Methods

• screenShot (name, bgColor, toSVG, svgAllCss), all arguments are optional
  • name: file name
  • bgColor: CSS color, png background color
  • toSVG: Boolean, (svg renderer) true: export as svg, false : export as png
  • svgAllCss: Boolean (svg renderer) true: include all styles in svg false: include only matched styles. This option is useful, for example to include hover actions on exported svg file

Node object

• id: node id. If not provided uses array index
• name: node name. If not provided uses: 'node node_id'
• _color: node color, e.g. red, #aa00bb,
• _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
• _color: link color, e.g. red, #aa00bb,
• _svgAttrs: Object, svg line attributes

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

TODO

• Touch support
• Optimization
• Zoom
• Canvas Render
• Nodes sprites

More Examples

• svg marks on links
• Links labels
• No-link forces
• Change node icon on the fly
