"WebIn VTK, filters are often used in a pipeline where each algorithm passes its output to the next filtering algorithm. In PyVista, we can mimic the filtering pipeline through a chain; attaching each filter to the last filter. In the following example, several filters are chained together: First, and empty threshold filter to clean out any NaN values. " - Pyvista threshold
