-### Installing module `canvas`
-
-Module `canvas` is only required if you need to run `vis.js` on `node.js` and require actual output. It is not required for regular usage in a browser.
-
-Currently, the unit tests use a mock object for canvas which has limited but adequate functionality. If `canvas` is installed, that will be used silently in place of the mock object.
-
-The issue with `canvas` is that it has an external dependency to `cairo`. This needs to be installed outside of the regular install as done by `npm`. Please consult [`node-canvas` github page](https://github.com/Automattic/node-canvas/wiki#desktop) for the correct installation procecure your platform
