 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 6to5ify -o vis-custom.js -s vis -x moment -x hammerjs
