 ## Task 2: Glyph-based Visualization (2P)
 In this task we want to enhance the visualization from above by rendering the vector field as glyphs. To achieve this, you can use the `vtkGlyph2D` class. To use this filter, you must set two inputs, one of them being a source. We ask you to use arrows as source, this will create glyphs in the shape of arrows. To complete this task successfully you have to play around with the scale and quantity of the glyphs.
