## What it is
A Visual Studio Code extension providing rich PlantUML support, including live diagram preview, export to multiple formats, syntax highlighting, snippets, and Markdown integration. It renders diagrams via a local PlantUML jar or a remote PlantUML server.

## Use cases
- preview plantuml diagrams in vscode
- export uml diagrams to png or svg
- syntax highlighting for plantuml files
- embed plantuml diagrams in markdown
- generate urls for plantuml diagrams

## When to avoid
- you don't use VS Code
- you need a standalone diagram editor without Java or a PlantUML server
- you rely on the deprecated code formatting feature

## Facets
- artifact type: plugin
- maturity: active
- function: editor, documentation, templating
- domain: developer-tools, documentation, text-editors
- platform: editor-plugin, cross-platform
- tags: plantuml, vscode-extension, diagram, uml, preview, syntax-highlighting
