We were looking for an alternative to Visio and came across a nice product called Lovely Charts.

We bought it to create web site maps but it would be just as useful for creating org charts, flow charts and other business related diagrams.

The desktop version help system needs a little work and we discovered that you need to use the backspace key instead of the delete key, but given it costs a fraction of the cost of Visio we're willing to cope with that.

However, our productivity is far higher with LovelyCharts than it is with Visio. We can create really good looking diagrams in seconds!

Unless you are a Visio "power user" we highly recommend LovelyCharts.
