Deep IT (www.deepitpro.com) has updated Diagrammix, a Mac OS X diagramming tool for building attractive diagrams with minimal effort, to version 2.6.0. The upgrade introduces an additional component, Vector Drawing Tools, that allows you to create your own shapes and lines and use them along with predefined shapes.

You can use Diagrammix as a fast business tool for illustration purposes. It offers several art elements and different connectors that let users prepare elements in vector drawing editors. Diagrammix has several palettes with elements specially designed for this release.

Once elements are connected by a line, they stay connected no matter how much you change them or move them around. That means the logical integrity of your diagram is preserved regardless of how you choose to position the elements. There are several connector styles: thin, thick, solid, dashed, dotted, with different arrows and colors, all with predefined styles. Work can be saved in a number of formats including JPEG, PNG, TIFF, PDF or copied to text processors via a clipboard.

Diagrammix costs US$19.95 and is available at the Mac App Store in the Graphics category. It requires Mac OS X 10.5 or later.
