Error generating quiver plot with Plots.jl

I am getting an error with the following MWE, which I think should work, based on the documentation for quiver in the Plots.jl package (v1.15.2). The error is: unexpected vi type Vector{Tuple{Float64, Float64}} for quiver. Does someone know what I am doing wrong? Thanks!

x = repeat(1:56,54)
y = repeat(1:54,56)
u = zeros(54,56)
v = zeros(54,56)

using Plots: quiver
plt = quiver(x,y,quiver=(u,v))
display(plt)
