I wouldn't say it does. The very first thing I did was to zoom out, and then understood that I cannot really use it without magnifying glass. So I installed xzoom to find out (unsurprisingly) that I cannot use it as well, because on that scale pixelation is strong enough for text to be unreadable, so the only solution would be to actually implement that feature in js.
Edit: browser zoom works well. There's a legend in the lower left.
