Inkscape is a Scalable Vector Graphics (SVG) editor. Most images you see on a computer are raster images made up of a bunch of dots. In other words, the lines you see on the page are really a series of small dots. If you zoom a lot, you’ll see a rough line consisting of a bunch of big dots.
SVG graphics contain a description of the image. For example, a line on the page consists of a command to the program such as “Draw a line of 1.0 width from point (0, 0) to point (6, 3).”
