Description

An implementation of the Circular Drawing Algorithm by Hongmei He & Ondrej Sýkora.

Click here for a demo.

Dependencies

  • Cytoscape.js ^3.2.0
  • avsdf-base ^1.0.0

Usage instructions

Download the library:

  • via npm: npm install cytoscape-avsdf,
  • via bower: bower install cytoscape-avsdf, or
  • via direct download in the repository (probably from a tag).

Import the library as appropriate for your project:

ES import:

import cytoscape from 'cytoscape';
import avsdf from 'cytoscape-avsdf';

cytoscape.use( avsdf );

CommonJS require:

let cytoscape = require('cytoscape');
let avsdf = require('cytoscape-avsdf');

cytoscape.use( avsdf ); // register extension

AMD:

require(['cytoscape', 'cytoscape-avsdf'], function( cytoscape, avsdf ){
  avsdf( cytoscape ); // register extension
});

Plain HTML/JS has the extension registered for you automatically, because no require() is needed.

API

When calling the layout, e.g. cy.layout({ name: 'avsdf-base', ... }), the following options are supported:

var defaultOptions = {
    // Called on `layoutready`
    ready: function () {
    },
    // Called on `layoutstop`
    stop: function () {
    },
    // number of ticks per frame; higher is faster but more jerky
    refresh: 30,
    // Whether to fit the network view after when done
    fit: true,
    // Padding on fit
    padding: 10,
    // Prevent the user grabbing nodes during the layout (usually with animate:true)
    ungrabifyWhileSimulating: false,
    // Type of layout animation. The option set is {'during', 'end', false}
    animate: 'end',
    // Duration for animate:end
    animationDuration: 500,   
    // How apart the nodes are
    nodeSeparation: 60
};

Build targets

  • npm run test : Run Mocha tests in ./test
  • npm run build : Build ./src/** into cytoscape-avsdf.js
  • npm run watch : Automatically build on changes with live reloading (N.b. you must already have an HTTP server running)
  • npm run dev : Automatically build on changes with live reloading with webpack dev server
  • npm run lint : Run eslint on the source

N.b. all builds use babel, so modern ES features can be used in the src.

Publishing instructions

This project is set up to automatically be published to npm and bower. To publish:

  1. Build the extension : npm run build:release
  2. Commit the build : git commit -am "Build for release"
  3. Bump the version number and tag: npm version major|minor|patch
  4. Push to origin: git push && git push --tags
  5. Publish to npm: npm publish .
  6. If publishing to bower for the first time, you'll need to run bower register cytoscape-avsdf https://github.com/iVis-at-Bilkent/cytoscape.js-avsdf.git
  7. Make a new release for Zenodo.
