What can we do to make ScottPlot better?
Add a vector field plottable, e.g.:

Does your proposed feature allow users to do new things in source code? If so, show us how you'd like to be able to use the new feature:

plt.PlotVectorField(Vector2[] vectors, double[] xs, double[] ys)

It might be valuable for the arrows to change in colour to indicate magnitude, as vector fields typically have scaled-down arrows so the plot remains readable

Conveniently, Microsoft provides vector types for 2, 3, and 4 dimensions: https://docs.microsoft.com/en-us/dotnet/api/system.numerics.vector2?view=netcore-3.1
