Stream plots are used to visualize a flow in vector fields. Examples from Science and Nature include fields of magnetic and gravitational forces and movement of liquid materials.
A vector field can be visualized in such a way where we assign a line and one or more arrows to every point. The intensity can be represented by the line length, and the direction by an arrow pointing in a particular direction.
Usually, the intensity of the force is visualized with the length of a particular streamline, but the density can also be used for the same purpose.
To visualize vector fields, we will use matplotlib's
matplotlib.pyplot.streamplot function. This function creates plots from streamlines of a flow, uniformly ...
