• Predefined propagator styles, vertex types, and symbols
• Support for typesetting labels and including external graphics
• Lightweight, cross-browser, and fully documented

jQuery.Feyn is released under the MIT license.

• Firefox 4+
• Chrome 7+
• Opera 11.6+
• Safari 5.1+
• IE 9+

A more detailed compatibility table for support of inline SVG in HTML5 can be found at caniuse.com/svg-html5.

To use jQuery.Feyn, the first thing you should do is to load the scripts. Then you can configure your desired Feynman diagram such as

<script>
  $(document).ready(function() {
    $('#container').feyn({
      incoming: {i1: '20,180', i2: '180,180'},
      outgoing: {o1: '20,20', o2: '180,20'},
      vertex: {v1: '100,140', v2: '100,60'},
      fermion: {line: 'i1-v1-i2,o2-v2-o1'},
      photon: {line: 'v1-v2'}
    });
  });
</script>

The jQuery ID selector $('#container') can also be replaced by any other CSS selector that applies to a unique block-level element in your document, which serves as the container of jQuery.Feyn's SVG output.
