Why represent the data twice? That's not minimalism. Besides, if you were the OP on an article, you couldn't tell the addition of even say, 5 points without the number itself, making the Y-meter useless. Plus, all data outside 0-400 is completely lost. Something with 401 votes looks exactly the same as 2000 votes.
Maybe minimalism isn't the real goal. The data might be represented twice, but functionally the representations are not redundant. The number provides maximum granularity, but the Y meter facilitates instantaneous comparisons of many stories simultaneously.
I'm not sold on the design overall but there is nothing in principle wrong with representing data in both a imprecise and precise form. A lot of user interfaces do this.
Some have three layers.
