It’s not often that I need to draw a diagram or a flowchart these days. My time is mostly consumed by more technically challenging tasks. And whenever I do have to produce some form of a chart, I usually fallback on to the Graphviz dot, which allows me to do something in literally seconds.
However, I’m pretty sure the day will (or, rather, return) when I’d need a tool to produce eye-pleasing diagrams and flowcharts. For that day, and for that day only, I’m leaving the link to SmartDraw here. It’s a commercial offering, but at $15/month for their cloud-hosted web-based application, it’s seems to be quite a bargain.
