I am looking for a free flow-charting web-app.
This is basically for creating flowcharts for a program's structure, and so, I would like (as many as possible):
- font, block and line colour options
- looping (ie. joining an arrow from one block back to another)
- free positioning (doesn't have to be in one vertical line)
- pictures (that I upload)
I need it to be free, online, exportable to any format (PDF is preferable), and cloud storage with the app is even better!
