SciPy : Scientific Python
SciPy, pronounced as "Sigh Pie," is an open-source library comprising a collection of mathematical algorithms, including minimization, Fourier transformation, regression, and other essential mathematical and scientific techniques. A significant portion of SciPy's functionalities are Python "wrappers," meaning they serve as interfaces for numerical and scientific libraries that were initially implemented in Fortran, C, or C++, seamlessly integrating these powerful functionalities into Python for efficient scientific computing.
SciPy
SciPy complements the Python NumPy extension and is an integral part of the NumPy stack. It enhances NumPy's capabilities by providing optimized and additional functions commonly used in N-dimensional array manipulation and Data Science tasks. SciPy further empowers the interactive Python session by offering high-level commands and classes for data manipulation and visualization, making it a popular choice among researchers in academia and industry. Notably, SciPy has played a crucial role in significant scientific achievements, such as the detection of gravitational waves by LIGO and the imaging of a black hole in galaxy M87 by the Event Horizon Telescope. Importantly, as SciPy builds on NumPy, importing SciPy in Python eliminates the need to separately import NumPy.

SciPy Constants
You can find a large collection of mathematical and physical constants in scipy.constants. These SciPy constants can be helpful when you are working with Data Science projects.
Spatial Data
Spatial data pertains to information that is represented in a geometric space, employing various techniques like Triangulation, Voronoi Diagram, and Convex Hulls of a set of points. These spatial computations are facilitated by utilizing the Qhull library, which enables efficient handling and processing of geometric data.
Triangulation example
In spatial data, a Triangulation of a polygon involves dividing the polygon into multiple triangles, allowing for the calculation of the polygon's area. The Delaunay() Triangulation is a method used to generate triangulations based on a set of points, creating a network of non-overlapping triangles that cover the space efficiently and are suitable for various spatial data analysis tasks.
