## What it is
DiagrammeR is an R package for creating, modifying, analyzing, and visualizing network graph diagrams using tabular data. Graphs are built from node and edge data frames and can be rendered in R Markdown documents, Shiny apps, or exported as images.

## Use cases
- visualize network graphs from tabular data in R
- analyze graph metrics like betweenness and degree
- embed network diagrams in R Markdown reports
- render interactive graphs in Shiny apps
- create flowcharts and diagrams programmatically
- export graph diagrams as image files
- identify articulation points and graph structures

## When to choose
- you work in R and need graph/network visualization from data frames
- you want to embed diagrams in R Markdown or Shiny
- you need graph analysis functions alongside visualization
- you prefer a declarative, pipe-friendly API for building graphs

## When to avoid
- you need large-scale graph processing beyond visualization
- you work outside the R ecosystem
- you need interactive web-based graph exploration with heavy interactivity
- you need a general-purpose plotting library for non-graph charts

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, charts
- domain: data-visualization, data-science, developer-tools
- platform: cross-platform
- tags: graph-theory, network-analysis, r-package, graphviz, property-graph, r-markdown, shiny, r
