Problem in Visualization for Sample code

[newton-raphson]

Describe the bug
np.float was a deprecated alias for the builtin float. To avoid this error in existing code, use float by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use np.float64 here.

To Reproduce
Steps to reproduce the behavior:

1. pip install geomdl
2. run the sample code to produce the code
3. AttributeError: module 'numpy' has no attribute 'float'.

   The aliases was originally deprecated in NumPy 1.20; for more details and guidance see the original release note at:

Expected Behavior

Configuration:

• macos M1
• python3.11
• pip - geomdl version/branch:

[Srallars97]

Got the same problem.

I fixed by changing l.71 in geomdl/visualization/VisMPL.py.

self.dtype = np.float

to
self.dtype = float
.

Solved it for me.

Same issue, the full stack trace from running the plotting example on the "Basics" page in the documentation gives:

`np.float` was a deprecated alias for the builtin `float`. To avoid this error in existing code, use `float` by itself. Doing this will not modify any behavior and is safe. If you specifically wanted the numpy scalar type, use `np.float64` here.
