The GeoChart display the formatted value in the hovercard, which can be
different than the metro-code.
In your example, you can replace the addRow line with the following line:
data.addRow([{v: '501', f: 'New York'}, 83.9]);
Here is a live example:

Notice that in the example I also use setCell which is another alternative.
