InkPlot is an extension (plugin) for the SVG Editor Inkscape to insert graphs from Gnuplot.
It allows you to
- preview the graph
- add it as SVG into Inkscape
- edit already generated graphs
- use a preamble file for reusable style and commands
- customize default settings in a config file
OriSVG attends to give some help to origami diagrams designers by providing markers, arrows, strokes and preformated diagrams in SVG language, and some Inkscape's plugins and scripts.
