Inkscape is a drawing program that creates vector graphics, or shape objects. Which is different from pixel graphics where the image is made from a grid of coloured dots. It has advanced functionality for creating professional artwork. Inkscape is a free, open source program. So if you want to try it you can download it from inkscape.org and install it right away.
Thumbs up for Inkscape. Surprisingly easy to use and has a pretty powerful feature that will automatically trace a raster image which I use surprisingly often.
