See the discussion here: [Plotting image data in Julia is much slower than MATLAB](https://discourse.julialang.org/t/plotting-image-data-in-julia-is-much-slower-than-matlab/79660)

It’s pretty easy to do a downsampling call yourself, and there are packages like [InteractiveViz.jl](https://github.com/org-arl/InteractiveViz.jl) that will do it for you.
