What is the General Chart Shape?

I think my chart is a splay, but I'm not sure. I also don't think it's a bucket.

Also, there's an aspect between Pluto, Uranus, and Mercury, but I'm not sure what it's called. I've read about Yods, T Squares, etc.. but I don't know if I have any of those type of aspect shapes in my charts.

I just need some help in figuring it out and what it means.

The NN is not a planet, which many astrologers would require to count something as a handle on the bucket. I'd call your chart a bowl shape. http://www.bobmarksastrologer.com/Bowl.htm

Your chart has a bowl shape, because North Node isn't a planet, so it doesn't count as the handle of a bucket chart at all. Not even splay, as all of the planets are situated within a half of a chart, and not distributed in trined signs.
