FlowCharts
Create graphical flowcharts:
draw.io is a great way to make quick and clean flowcharts.
Ascii flow charts
To create ascii based flowcharts use:
You can use these directly in emails, and especially in code comments.
Or you can convert them into graphics using the following two tools:
Ascii to PNG
To convert ascii flowcharts into normal images use ditaa
I've added ditaa to util, here $env:util\ditaa0_9\
The file "using_ditaa.bat" gives this example:
java -jar .\ditaa0_9.jar hey.txt -o -S -s 2
Which turns "hey.txt" into "hey.png"
Cartoony Ascii flowchart to png
