Add images in readme

[KronosTheLate]

The following code:

using CircleFit
using GLMakie

r = 1
N = 20
σ = 0.05
θs = range(0, 360, N+1)[begin:end-1]
xs = r * cosd.(θs) + randn(N)*σ
ys = r * sind.(θs) + randn(N)*σ

fig, ax, plt = scatter(xs, ys, label="Noisy points", color=Cycled(2))
ax.aspect=DataAspect()
x_center_fit, y_center_fit, r_fit = CircleFit.pratt(xs, ys)
scatter!(x_center_fit, y_center_fit, label="Fitted Center", color=:black, markersize=20)
θs_fit = range(0, 360, 200)#[begin:end-1]
lines!(r_fit * cosd.(θs_fit), r_fit * sind.(θs_fit), label="Fitted cicle", color=:black)
leg = Legend(fig[1, 2], ax)
ax.title="True radius = $r. Fitted radius = $(round(r_fit, sigdigits=5))"#$N points on circle with radius $r.\nAdded noise with σ=$σ"
display(fig)

Procudes the following plot:

I am sure that such visual examples would be very nice to have in the readme (or on the documentation page).

By the way, this is something that anyone can do, and I am not specifically asking the maintainer(s) of this package to do this. View it more like a todo-note for anyone to take.
