This is one of my favorite Julia packages! A fast plotting utility that outputs right to the terminal is one of those things that I didn't realize I needed until I found it.
Having inline plots in the terminal - especially things like histograms which just work - is often quite handy. And it just works over an ssh connection.
Also, recently, Julia changed its sparse matrix display to show a picture of the sparse matrix (spy plot) using braille characters!
julia> a = sprand(20,20,0.2)
20×20 SparseMatrixCSC{Float64,Int64} with 67 stored entries:
