GR vs GLVisualize comparison?

@Juan: and InspectDR doesn’t work either: […]

What versions are you using?

It worked for me with Julia v0.6.0-rc2.0 + Windows 7, and the following:

julia> Pkg.installed("InspectDR")
v"0.2.0"

julia> Pkg.installed("Plots")
v"0.12.0"

Also: Have you recently done an update:

julia> Pkg.update()

?
