Need help with very basic plotting

$

Hello,

I am trying to learn Julia. When I type in the basic plotting example given at
Tutorial · Plots, namely the code below copied directly
from the link given above.

import Pkg; Pkg.add(“Plots”)
using Plots
x = 1:10; y = rand(10); # These are the plotting data
plot(x, y)

I obtain no plot and the following error.

Error evaluating PlotExampleDoesNotWork.jl

LoadError: UndefVarError: plot not defined

in expression starting at /private/tmp/PlotExampleDoesNotWork.jl:4

top-level scope at PlotExampleDoesNotWork.jl:4

include_string(::Function, ::Module, ::String, ::String) at loading.jl:1088

I get the same error with or without the first line: import Pkg; Pkg.add(“Plots”)

What am I missing ?

Thank you and my apologies for such a basic question.
