2D plot throws error program not linked

[SebastianM-C]

Hello! I tried to plot some random 2D points with the following code in REPL

using Plots
glvisualize()
plot(rand(10),rand(10))

and I got the following error:

If I try to plot in 3D, it works (with plot3d(rand(10),rand(10),rand(10))). Am I missing something? My OpenGL info is:

and I am on the master branch of GLVisualize

I can see how that's happening, since I forgot a convert in the line code - but this was working fine previously and seems to be a regression in Plots.jl. Not sure why that popped up suddenly! I opened a PR to fix it!

Thanks!
