Output and view graphs in various formats

dot clj

(dot g f & args)

Writes graph g to f (a string or File) in DOT format. It passes args to dot-str.

dot-str clj

(dot-str
  g
  &
  {:keys [graph-name node-label edge-label] :or {graph-name "graph"} :as opts})

Renders graph g as a DOT-format string. It calls (node-label node) and (edge-label n1 n2) to get labels for nodes and edges. Weights become edge labels unless a label is specified. Labels include attributes when the graph satisfies AttrGraph.

render-to-bytes clj

(render-to-bytes g & {:keys [alg fmt] :or {alg "dot" fmt :png} :as opts})

Renders graph g in an image format with GraphViz. Returns data as a byte array. GraphViz's 'dot' or a specified algorithm must be in the shell path. Algorithms include :dot, :neato, :fdp, :sfdp, :twopi, and :circo. Formats include :png, :ps, :pdf, and :svg.

view clj

(view g & {:keys [fmt] :or {fmt :png} :as opts})

Converts graph g to a temporary image file with GraphViz. Opens the file in the default viewer for the current desktop environment. GraphViz's 'dot' or a specified algorithm must be in the shell path. Algorithms include :dot, :neato, :fdp, :sfdp, :twopi, and :circo. Formats include :png, :ps, :pdf, and :svg.
