I was looking for a diagram designer and I was in hurry. Thus I have no time to download any well known diagram designer applications. I went to Google and searched ‘diagram designer’ and got an application with identical name: Diagram Designer.
I just need a few click to install and run Diagram Designer. Very nice application despite of its small size. It displays object tree, canvas and some common symbols for flow chart/diagram.
The application really fit my needs. The only missing thing is a feature to export the diagram into PDF file, but that’s OK.
