Product Overview

Graphviz

Description: Graphviz is an open source graph visualization software used for representing structural information as diagrams of abstract graphs and networks. It provides useful features for creating a variety of graph types like directed graphs, undirected graphs, hierarchies, and more.

PlantUML

Description: PlantUML is an open-source tool for creating UML diagrams from plain text. It supports all standard UML diagrams like use case diagrams, class diagrams, sequence diagrams, etc. PlantUML allows users to write simple textual descriptions which are then transformed into UML diagrams.
