Apparently, I could create a logic tree using programs such as MS PowerPoint or Paint. It is not a dedicated flowchart or diagramming package, but its core use case--i.e., efficient and aesthetic rendering of objects comprised of nodes and edges, obviously subsumes flowchart drawing--particularly because its api allows the user to set various constraints on the layout to encourage rendering in the various formats--eg, you can require all nodes of the same level (same number of parents from the root) to be rendered in a single center-aligned row. It is a Domain-Specific language for producing domain-specific visualizations, particularly for data analysis. The middle level users can use the matplotlib framework to create dots for scatter plots. .
