ComplexVectorPlot
ComplexVectorPlot[f,{z,z_{min},z_{max}}]
generates a vector plot of the vector field {Re[f],Im[f]} over the complex rectangle with corners z_{min} and z_{max}.
ComplexVectorPlot[{f_{1},f_{2},…},{z,z_{min},z_{max}}]
plots several vector fields.
Details and Options
 ComplexVectorPlot is also known as field plot and direction plot.
 ComplexVectorPlot displays a vector field by drawing arrows. By default, the direction of the vector is indicated by the direction of the arrow, and the magnitude is indicated by its color.
 ComplexVectorPlot omits any arrows for which f does not evaluate to a complex number.
 ComplexVectorPlot[f,{z,n}] is equivalent to ComplexVectorPlot[f,{z,nn I,n+n I}].
 ComplexVectorPlot treats the variable z as local, effectively using Block.
 ComplexVectorPlot has attribute HoldAll and evaluates f only after assigning specific numerical values to z. In some cases, it may be more efficient to use Evaluate to evaluate f symbolically first.
 ComplexVectorPlot has the same options as Graphics, with the following additions and changes:

AspectRatio 1 ratio of height to width ClippingStyle Automatic how to display arrows outside the vector range EvaluationMonitor None expression to evaluate at every function evaluation Frame True whether to draw a frame around the plot FrameTicks Automatic frame tick marks Method Automatic methods to use for the plot PerformanceGoal $PerformanceGoal aspects of performance to try to optimize PlotLegends None legends to include PlotRange {Full,Full} range of x, y values to include PlotRangePadding Automatic how much to pad the range of values PlotTheme $PlotTheme overall theme for the plot RegionFunction (True&) determine what region to include RegionBoundaryStyle Automatic how to style plot region boundaries RegionFillingStyle Automatic how to style plot region interiors VectorAspectRatio Automatic width to length ratio for arrows VectorColorFunction Automatic how to color arrows VectorColorFunctionScaling True whether to scale the argument to VectorColorFunction VectorMarkers Automatic shape to use for arrows VectorPoints Automatic the number or placement of arrows VectorRange Automatic range of vector lengths to show VectorScaling None how to scale the sizes of arrows VectorSizes Automatic sizes of displayed arrows VectorStyle Automatic how to style arrows WorkingPrecision MachinePrecision precision to use in internal computations  The individual arrows are scaled to fit inside bounding circles around each point.
 VectorPoints{c_{1},c_{2},…} uses the complex numbers c_{1}, c_{2}, etc.… as the points at which to draw the arrows.
 VectorScaling scales the magnitudes of the vectors into the range of arrow sizes s_{min} to s_{max} given by VectorSizes.
 VectorScaling>Automatic will scale the arrow lengths depending on the vector magnitudes:
 The arrow markers given by VectorMarkers are drawn inside a box whose width and length are in the proportion specified by VectorAspectRatio.
 Common markers include:

"Segment" line segment aligned in the field direction "PinDart" pin dart aligned along the field "Dart" dartshaped marker "Drop" dropshaped marker  VectorColorFunction>None will draw the arrows with the style specified by VectorStyle.
 The arguments supplied to functions in RegionFunction and VectorColorFunction are z and f.

Applications (7)
For a complex function f, plot {Re[f],Im[f]}:

Identify poles and zeros. Poles are visible at and :
The zeros at and are more readily visible if the vectors are scaled:
Vectors in the field rotate twice along the unit circle surrounding the zero of the function at the origin, which implies that has a double zero at the origin:
The function has a pole of order 2 at since has a double zero:
