It's a nice chart but fairly slanted towards nxt. (of course it's expected though)
For instance CounterParty clearly has smart contracts, DAC's, Multisig, Voting system, Marketplace, market pegs, User registered accounts right now However those are marked with a cross on the chart. For some of those same features on NXT that actually don't yet exist they are marked as "work in progress'. It would be nice to make it completely unbiased but admittedly wishful thinking.
Also echoing the above sentiment. CoinGecko paints a more accurate picture of the "top" coins than coinmarketcap does.
