I miss my NaNo progress graph... other options?

It's not a simple thing, actually. Those NaNo progress indicators used (I think) cgo or Javascript to point back to the data on the Nano site.

If you want something like that, you're going to need to host it somewhere.

I think a simple graph image might be fairly easy.

It's not really one that you can show off in your signature, but this graph here is not only a yearly tracker with different designs, but the first page shows you a graph that automatically updates as you add to it. It was created for 2012, and she also has one for 2011, but she doesn't have an updated one for 2013 or 2014, unfortunately. But I'm using the 2012 and it doesn't really make much of a difference, to be perfectly honest. The only reason you would need an one is if the chart has days (Sunday-Saturday) and this chart doesn't require them, so a new one for every year is pretty unnecessary.
