vsfplot is a 2D vector and scalar field plotter. It features Line Integral Convolution (LIC) on data, curvilinear scaled arrows following the flow lines, a mixed mode (scalar field map with overlaid vector field), handling of missing data to not interfere with the flow lines, generation of Scalable Vector Graphics (SVG) files (which are easily editable and convertible while preserving the best quality for inclusion in a PDF scientific article), and a color palette designed so the flows are uniformly readable when printed as greyscale.
