Fun with SAS ODS Graphics: Apollo 11 EarthRise Bubble/Ellipse Plot

Earthrise (Bubble/Ellipse Plot)Earthrise (Apollo 11)

Figured I should do something to mark the 50th anniversary of the Moon Landing, even if it's only a silly Earthrise bubble/ellipse plot!

Nice. How about adding some textures using images?

Good idea - haven't tried this technique, but will look into it. In the meantime, I borrowed from your 2017 solar eclipse post and added some "stars" with a scatter plot. Also tossed in some random "craters" with a bubble plot.

Earthrise (now with scatterplot stars and bubbleplot craters!)
