I was recently asked to make a couple of charts illustrating various policies here at the ELI. Having never done that, the first thing I did was look for open source tools.
Dia is extremely intuitive to use, and a great way to make flowcharts, organizational charts, and other diagrams. It could certainly be useful in creating class materials and visual prompts, in addition to doing administrative work. I’m always on the lookout for useful open source software and Dia is a great addition to my list.
