Here is a fun simple way to impress your boss, with Lovely Charts, you can very quickly create flowcharts, network diagrams, sitemaps and wireframes. I know the diagram above means nothing but I created it and exported it as an image in only a few minutes
Other similar online programs include Gliffy, Flowchart.com and Draw that enable you to create diagrams and more in your
browser with drag-and-drop functionality. The main differentiator
between LovelyCharts and other online services is that it actually
makes your complex processes look incredibly good. Better yet, it’s
completely free and since last week, out of beta.
In terms of features, LovelyCharts has pretty much all the basics
covered, but you really need to try it out to get a feel of how rich
the web-based app really is even with its relatively simple feature
set. You can draw, align, insert symbols and icons, snap, zoom, import
& export, and so on - for a good overview, check the tour and the video demo.
I think one improvement that could be made would be alow you to upload a custom symbol, but other than that I think it really works well.
LovelyCharts was developed by RIA developer and user architect Jérôme Cordiez.
