## What it is
PGF is a TeX macro package for programmatically generating vector graphics, with TikZ as its user-friendly syntax layer. It is platform- and format-independent and works with major TeX backend drivers such as pdftex and dvips.

## Use cases
- draw diagrams and figures directly in LaTeX documents
- create publication-quality plots and charts in TeX
- generate vector graphics programmatically for academic papers
- draw graphs, trees, and flowcharts in LaTeX
- produce animations and SVG graphics via dvisvgm
- typeset technical illustrations without external drawing tools

## When to choose
- you are writing LaTeX documents and need precise, reproducible vector graphics
- you want diagrams version-controlled as plain text alongside your TeX sources
- you need publication-quality figures for papers, theses, or books

## When to avoid
- you need interactive or WYSIWYG drawing tools
- your project is not TeX/LaTeX based
- you need raster image editing or photo manipulation

## Facets
- artifact type: library
- maturity: stable
- function: data-visualization, graphics, templating
- domain: graphics, documentation, data-visualization, developer-tools
- platform: windows, cross-platform
- tags: tex, latex, tikz, vector-graphics, diagrams, macro-package, linux, macos
