 The default bundle `vis.js` is standalone and includes external dependencies such as *hammer.js* and *moment.js*. When these libraries are already loaded by the application, vis.js does not need to include these dependencies itself too. To build a custom bundle of vis.js excluding *moment.js* and *hammer.js*, run browserify in the root of the project:
 
-    $ browserify index.js -t [ babelify --presets [es2015] ] -o dist/vis-custom.js -s vis -x moment -x hammerjs
