AjaxSketch is basically a pared down version of Illustrator or Inkscape — perfect for creating quick charts and diagrams from scratch. It includes autoshapes, pencil mode, and text for creating the basics. You can also edit by resizing, rotating, changing background or pen color, and altering opacity.

Inkscape is an Open Source vector graphics editor, with capabilities similar to Illustrator, Freehand, CorelDraw, or Xara X using the W3C standard Scalable Vector Graphics (SVG) file format. Supported SVG features include shapes, paths, text, markers, clones, alpha blending, transforms, gradients, patterns, and grouping. Inkscape also supports Creative Commons meta-data, node editing, layers, complex path operations, bitmap tracing, text-on-path, flowed text, direct XML editing, and more. It imports formats such as JPEG, PNG, TIFF, and others and exports PNG as well as multiple vector-based formats.
