Inkscape

Inkscape is an open source drawing tool with capabilities similar to Illustrator, Freehand, and CorelDraw that uses the W3C standard scalable vector graphics format (SVG). With Inkscape, artists can freely create professional vector art for electronic and print illustration. Vector drawing applications like Inkscape work with nodes (points,) curves, lines and shapes to create visual illustrations. Inkscape contains a full set of tools, including both industry standard and unique, to create and edit the nodes, curves, lines and shapes of vector art. Objects can be rotated, sized, skewed, proportioned, filled and stroked. The position of individual points of a shape or line can be manipulated in precise detail. Advanced visual effects, like gradient and transparency, and boolean operations, enable Inkscape users to complete any vector drawing task. Original features, such as direct access to the document SVG source code, set Inkscape apart from other vector art editors.
