Data Sets
=========
Datasets are any spatially referenced information and usually consist of
geometrical representations of a surface or volume in 3D space.
In VTK, this superclass is represented by the :vtk:`vtkDataSet` abstract class.
In VTK, datasets consist of geometry, topology, and attributes to which PyVista
provides direct access:
* Geometry is the collection of points and cells in 2D or 3D space.
* Topology defines the structure of the dataset, or how the points are connected
to each other to form a cells making a surface or volume.
* Attributes are any data values that are associated to either the points or
cells of the dataset
All of the following data types are listed subclasses of a dataset and share a
set of common functionality which we wrap into the base class
:class:`pyvista.DataSet`.
For additional details regarding PyVista's data model, please see
:ref:`pyvista_data_model`.
Dataset API Reference
---------------------
The :class:`pyvista.DataSet` class holds attributes that
are *common* to all spatially referenced datasets in PyVista. This
base class is analogous to VTK's :vtk:`vtkDataSet` class.
The :class:`pyvista.DataSetAttributes` class contains the methods to access
arrays associated with cells, points, and the DataSet in general (fields).
