DiagrammeR is a R package for creating diagrams.

DiagrammeR is a R package for creating graph diagrams using text in a Markdown-like syntax. Mermaid (.mmd) or Graphviz (.gv) files can be edited directly within the IDE for .

Graphviz attributes allow you to style your Graphviz graph. Combinations of attributes for nodes, edges, clusters, and for the entire graph provide for highly-customized layouts.

All Graphviz attributes are specified by name-value pairs. Thus, to set the fillcolor of a node abc, one would use

abc [fillcolor = red] Similarly, to set the arrowhead style of an edge abc -> def, one would use

abc -> def [arrowhead = diamond] Quotation marks are important only for multiword attributes, such might be used in the label attribute.

Features The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in useful formats, such as images and SVG for web pages; PDF or Postscript for inclusion in other documents; or display in an interactive graph browser. Graphviz has many useful features for concrete diagrams, such as options for colors, fonts, tabular node layouts, line styles, hyperlinks, and custom shapes.

Roadmap dot - "hierarchical" or layered drawings of directed graphs. This is the default tool to use if edges have directionality.

neato - "spring model'' layouts. This is the default tool to use if the graph is not too large (about 100 nodes) and you don't know anything else about it. Neato attempts to minimize a global energy function, which is equivalent to statistical multi-dimensional scaling.

fdp - "spring model'' layouts similar to those of neato, but does this by reducing forces rather than working with energy.

sfdp - multiscale version of fdp for the layout of large graphs.

twopi - radial layouts, after Graham Wills 97. Nodes are placed on concentric circles depending their distance from a given root node.

circo - circular layout, after Six and Tollis 99, Kauffman and Wiese 02. This is suitable for certain diagrams of multiple cyclic structures, such as certain telecommunications networks.
