Subject: [PATCH] Warning if using frozen props

Adds a warning if the passed in data prop is `Object.freeze`'d.

This is important since several React state managers return values that are frozen (in my case, Apollo). Currently, this just causes the plot to completely fail to render and gives no indication as to what's wrong.
