Im trying to create a triangulation (triangle Plot) plot and dont even know how to do ist can someone help please?  
using VoronoiDelaunay  
using GeometricalPredicates  
using DataFrames, Plots  
pyplot()

#mit unterer Aussenlinie initialisieren  
x = collect(-1:0.1:1)

y = -1\*ones(size(x))

#obere Aussenlinie hinzufuegen  
xtemp = collect(-1:0.1:1)  
ytemp = 1\*ones(size(x))

x = [x’ xtemp’]  
y = [y’ ytemp’]

#rechte Aussenlinie hinzufuegen  
ytemp = collect(-1:0.1:1)  
xtemp = 1\*ones(size(ytemp))

x = [x xtemp’]  
y = [y ytemp’]

#linke Aussenlinie hinzufuegen  
ytemp = collect(-1:0.1:1)  
xtemp = -1\*ones(size(ytemp))

x = [x xtemp’]  
y = [y ytemp’]

#zufaellige Innenpunkte hinzufuegen  
xtemp = 2_rand(1,500)-ones(1,500)  
ytemp = 2_rand(1,500)-ones(1,500)

x = [x xtemp]  
y = [y ytemp]  
vec(x)  
vec(y)  
##Delaunay-Triangulierung hinzufuegen  
plot(tess) = DelaunayTessellation(x,y)  
##Triangulierung plotten

Mit `x,y`, zur triangulierung kann mann auch `MiniQhull` und `Makie` benutzen.

```plaintext
using MiniQhull, Makie
p = [x;y]
t = delaunay(p)
scene = mesh(p',t')
wireframe!(scene[end][1], color = (:red, 0.6), linewidth = 3)

```
