SVG stands for Scalable Vector Graphics. This is an XML-based image format which I use for constructing scientific diagrams as well as various astronomical maps (star charts, planet paths, Moon phases, etc.). The image remains sharp even when magnified (or reduced) many times. No pixellation! I am not an expert so I am continually having to look up how to create various elements. This section contains a bunch of my crib sheets so that I can quickly remind myself how to do various things. Like arcs. Especially arcs.
ATTENTION! This is not an all-singing, all-dancing reference manual on SVG. It is just a collection of the various instructions that I find useful for the kinds of images that I produce.
ATTENTION! Not all browsers support all elements and attributes, nor do they necessarily render them identically to one another.
