@freemo I use graphviz regularly to collaborate and communicate ideas expressed by graphs, e.g. dataflow diagrams and flow charts. In meetings I live edit and share a preview while keeping up with the flow of discussion. The DOT language is simple, efficient for data entry, and expressive. It is also plaintext and I can manage changes in source control. https://graphviz.org/
