# D2 Diagram Creator

D2 Diagram Creator is a skill that can directly convert natural language descriptions into high-quality D2 diagram code and image files. After installation, you only need to describe the desired diagram structure in text, and it will automatically generate it for you.

Whether it's a flowchart in academic writing, a model architecture diagram in scientific illustration, or a module relationship diagram when understanding a new open-source project, you no longer need to draw it manually step by step.
