I'm looking at the balance of this wallet address: https://etherscan.io/address/0x9a77d0900323b5f2b6cff6138569846406cf7456
There is an IN transaction from Poloniex to this wallet of ~33 ETH, then an OUT transaction to The DAO of ~33 ETH, then an IN transaction of 1 ETH. Wouldn't the balance therefore be ~1 ETH? Why does the balance on this account show as ~34 ETH?
If the DAO was refunded to this wallet and that is why the balance is higher, where is this shown?
I not a user of Coinbase, but from my common sense theory, they settle your balance only on at an outgoing transaction to reduce transactional expenses and to have an ability to exchange your ether balance to other currencies. If it's in your wallet and only you have a key to that wallet they can't spend your ether.
It looks like an attempt to visually represent / track the downstream flow of transactions from one account to the next. In the example you asked about, the visualizer shows 3 transactions coming out of the initial account, and if you click on the little blue dot right before each of the three destination addresses, it will show you what further transactions flowed out of these addresses. It does not appear that the transactions listed for each address are comprehensive because when I entered the original "from" address in the search bar of etherscan, it had several more outgoing transactions than those represented in the visualizer.
Below is the visual of your example, after I clicked on the destination addresses. I didn't click on everything, but just wanted to give you the idea.

There is actually one more transaction you are missing, which can be found on the "internal transactions" tab:
https://etherscan.io/address/0x9a77d0900323b5f2b6cff6138569846406cf7456#internaltx
When you include this transaction, you will see that the books balance again.
Internal transactions are those sent by a contract instead of directly from a Externally Owned Account ("EOA" for short). Because they happen "a little further in" to the series of events triggered by some original action an EOA took, they take just a little more work to be identified, and not all block explorers show them. To reflect this different status (as well as the fact that the internal transactions which will eventually result from a currently unconfirmed transaction can't be reliably predicted), Etherscan shows the transaction on a separate tab. But the balances they transfer are regular ether, just like everything else!
