D2 Studio is a diagramming tool designed for developers, offering both a text-to-diagram language (D2) and a GUI editor. It aims to replace general-purpose diagramming tools with a solution that integrates seamlessly into developer workflows. D2's syntax is designed for software architecture, allowing users to define diagrams as code, enabling version control, collaboration, and automation. The bidirectional editing feature allows users to switch between text and visual editing, with changes synced in real-time. D2 features a custom layout engine optimized for software architecture diagrams, automated formatting, syntax highlighting (with extensions for VSCode and Vim), theming, and icon integration. The tool supports multi-layered, interactive diagrams to manage complexity and abstraction.
