A Density plot is a kind of heat map that represents magnitude or individual values as a color.
Similar is a Contour Plot, which is a kind of contour map.
A Surface plot (Plot3D) shows its 3rd or “height” dimension in a way that is projected onto a 2-dimensional surface.
ComplexPlot and ComplexPlot3D use color to visualize complex-valued functions in two and three dimensions, respectively.
