vue-d3-network on Vue 3 (alpha)

Vue component to graph networks using d3-force

Warning

This version has been thoroughly tested and is in active use in a production env of a Nuxt 3 project. BUT only the SVG graph with touch support & nodes selection. The screenshot feature has not been tested. Neither the canvas. Nor any of the tests have been updated. Linter fails (event though it shouldn't) - but again, no time has been spent on it. This is the result of us having to ship Nuxt 3 upgrade on a deadline.

simCb: Function(sim) -> sim, d3 simulation formatter

customForces: Object: { [d3Function]:args }

options:

Events

• node-click: fired when click 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

• [x] Touch support
• [ ] Optimization
• [ ] Zoom (though there's an excellent fork implementing this)
• [x] Canvas Render
• [x] Nodes sprites

More Examples

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