Fix for preventDefault issue

[zipelkopf]

Hi, when connecting any dot, the follwoing error is raised in console (at least in Chrome):
Unable to preventDefault inside passive event listener due to target being treated as passive.

This can be fixed by simply adding the following code into you CSS.

svg {
  touch-action: none;
  }

P.S. I'm using v1.0.1

Thanks for the plugin :-)
