How might I go about determining the network usage on Ethereum?

I've been sort of curious about dapps and other tokens running on the ethereum network. Is there a website that shows me all of this data?

Like which dapps are using the most gas/clogging the network. I remember seeing posts about cryptokitties "clogging" the network but never saw how they figured that out. I'm curious how others figured this out!
