jquery.graphviz.svg

jQuery plugin to make Graphviz SVG output more interactive and easier to navigate. Makes it easy to have features like:

  • Highlight nodes/edges
  • Zoom in/out
  • Graph navigation - select linked nodes
  • Fancy UI tooltips; bootstrap supported out the box
  • Move things forward/back in the graph

Have a look at the demo: https://cdn.rawgit.com/mountainstorm/jquery.graphviz.svg/master/demo.html

Documentation

Create a node where you want your SVG graph to be displayed. Typically you will want to:

  • set its size (width/height/top/bottom etc)
  • set it as a positioning root; set positioning: relative or somethign else
  • enable overflow: scroll

Something like this works pretty well: <div id="graph" style="width: 100%; height: 100%; overflow: scroll; position: relative;"></div>

Next includes the css, and javascript: <link rel="stylesheet" href="css/graphviz.svg.css">

<script type="text/javascript" src="js/graphviz.svg.js"></script>

Then init the node as a Graphviz object:

$(document).ready(function(){
    $("#graph").graphviz({
        url: "demo.svg", 
        ready: function() {
            var gv = this
        }
    });
});

Depending on the options passed this will load, adopt and setup the Graphviz generated SVG under #graph and call your supplied ready function when the setup is complete.

Options:

  • url: if present the url to fetch the svg from
  • svg: raw SVG (xml) data to adopt
  • shrink: the amount to shrink nodes by; this gives a nice gap between nodes and edges. Default '0.125pt'
  • tooltips: object containing callbacks for init, show, hide and update. Default implementation uses bootstrap
  • zoom: enable shift-scroll zoom. Default true
  • highlight: object containing callbacks for selected, unselected; Default dims color of unselected
  • ready: callback when setup is complete. Will be asyncronous if loading svg from a url

The demo (demo.html) and the source (GraphvizSvg.DEFAULTS) show how these work in detail.

There are also other methods you can call to navigate the graph, select elements, highlight, move etc. To access these you need to get the 'graphviz.svg' object from the jQuery element you initialized ($('#graph').data('graphviz.svg')); it is also supplied as this to the ready callback.

GraphvizSvg.nodes() Returns all node DOM elements

GraphvizSvg.edges() Returns all edge DOM elements

GraphvizSvg.nodesByName() Returns an object mapping graphviz node names to its DOM element

GraphvizSvg.edgesByName() Returns an object mapping graphviz edge names to its DOM element

GraphvizSvg.linkedTo(node, includeEdges) Returns a jQuery set of DOM elements linked to node; if includeEdges is true if also includes the edges

GraphvizSvg.linkedFrom(node, includeEdges) Returns a jQuery set of DOM elements linked from node; if includeEdges is true if also includes the edges

GraphvizSvg.linked(node, includeEdges) Returns a jQuery set of DOM elements linked with node (in an undirected graph); if includeEdges is true if also includes the edges

GraphvizSvg.tooltip($elements, show) Show/hide tooltips on the SOM elements in the $elements set

GraphvizSvg.bringToFront($elements) Brings the DOM elements in the jQuery set to the front

GraphvizSvg.sendToBack($elements) Sends the DOM elements in the jQuery set to the back

GraphvizSvg.highlight($nodesEdges, tooltips) Highlight the DOM elements in $nodesEdges, if tooltips is true also show tooltips. If no nodes are passed it unselects all nodes/edges

  • jquery-2.1.3.js; for everything
  • Bootstrap; for default tooltips - not needed if you disable/dont use your own tooltips
  • jquery.color.js; for default highligh coloring - not needed it you supply your own
