#35

Thanks @wgui for your contribution and your fix is exactly what needs to be done.

But could you do 2 things:

1. remove the change you've made on dist/Visualizer.js since that should not have changed.
2. Edit your commit message to follow
   -- Or just use that one: fix(cli): Add support for --proxies argument

Your change didn't get through... Are you going to push something else?
