Remove warnings logged for XYPlot while running the JS test suite

[EshaanAgg]

When running the complete JS test suite, the above warning is logged in the console due to using the componentWillReceiveProps lifecycle hook in the XYPlot component. Since we are using this component directly from the react-vis library, we can't update it's implementation. Maybe bumping the version of the library can fix the issue (?)

Yes, this is kind of a known issue. It is unclear whether react-vis is still maintained enough such that we can hope for a fix of uber/react-vis#1084 / uber/react-vis#1356.

We have #570 for tracking the question of what to do with react-vis, and I don't think we can anything do about the mentioned warnings besides from waiting for a new version of react-vis or replacing it with something else. So I will close this issue here, but nevertheless bringing up topics like this is appreciated!

Yes sir, sounds good! Thanks for the response and all the background to the issue!
