Quiver plot
Definition
Visual representation of a vector field, where arrows are used to depict the magnitude and direction of a vector at different points in a space, essentially showing "flow" by drawing arrows that indicate both the direction and strength of a quantity at each location on a plot; often used in fields like physics and engineering to visualize things like wind patterns, fluid flow, or electric field gradients.

Describe the variables, the direction and length of the arrows, and any clear flows, clusters, or changes in magnitude across the plotted area.

"Two quiver plots compare calibration residual vector fields using x and y components of the star vector. Panel a shows long arrows radiating outward from the center, indicating large systematic residuals from incorrect focal length. Panel b shows much shorter and scattered arrows after parameter optimization, indicating reduced residual magnitude and improved calibration accuracy."
