Diagram Designer is a simple vector graphics editor for creating flowcharts, UML class diagrams, illustrations and slide shows.
This vector designer helps you to create diagrams using a customizable template object palette. Just drag and drop objects from the palette into your diagram. Then double click an object in order to enter text. A useful spell-checker can be added and check your spelling by clicking "Diagram --> Spell-Checker" or using Ctrl+F7 buttons. There are other tools which can help you plot mathematical expressions, solve equations with an advanced "pocket" calculator, edit bitmap images etc.
Diagram Designer can import or export to WMF, EMF, BMP, JPEG, PNG, MNG, ICO, GIF and PCX images and works fine under Windows 98/ME/2000/XP/Vista.
Diagram Designer is an installable application but universal extractor can help you to make it portable. Download "DiagramDesignerSetup.exe" and use universal extractor to extract Diagram Designer's files in a folder of your choice. Then double click "DiagramDesigner.exe".
