I am looking for command line utility to generate Gantt diagram from textual representation in Graphviz way or in the way that Blockdiag does. I'm aware of Mermaid and NodeJS, and I know that Plantuml is planning to add Gantt diagram implementation.
Something similar is possible achieve using Gnuplot, but the syntax is quite specific and complex (have a look at this example)
I want to do something like:
gantt source.txt > image.png
Is there any tool available now?
