The code is a bit golfed and I’m not exactly sure how to count the lines.

```julia
using Plots
function mandelbrot(z) w = z
    for n in 1:74
        abs2(w) < 4 ? w = w^2 + z : return n
    end; 75
end
x, y = range(-0.65, -0.45; length=1600), range(0.51, 0.71; length=1600)
heatmap(x, y, -log.(mandelbrot.(x' .+ y .* im)); aspect_ratio=1)

```

This is the output:  
 ![mandel](https://global.discourse-cdn.com/julialang/original/3X/8/7/8769e2dd45c4d883a921076f36a0413e96fb03cf.png)
