A wrapper of graphviz's underlying c libraries gvc and cgraph.
A high level wrapper for rendering graphs can be found at com.phronemophobic.clj-graphviz/render-graph.
For direct access to gvc and cgraph, check out the com.phronemophobic.clj-graphviz.raw.
Built with clong.
Leiningen dependency:
[com.phronemophobic/clj-graphviz "0.6.4"]deps.edn dependency:
com.phronemophobic/clj-graphviz {:mvn/version "0.6.4"}clj-graphviz needs libgraphviz to installed on the system. The native dependencies can either be installed using a package manager or by including the maven dependency for your platform and architecture.
Including multiple platforms and architectures is fine, but it will increase the size of your dependencies
com.phronemophobic.cljonda/graphviz-darwin-aarch64 {:mvn/version "2.50.0-0.9.5"}
com.phronemophobic.cljonda/graphviz-darwin-x86-64 {:mvn/version "2.50.0-0.9.5"}
com.phronemophobic.cljonda/graphviz-linux-x86-64 {:mvn/version "2.50.0-0.9.5"}Examples:
Linux
sudo apt install libgraphviz-dev
Mac
sudo port install graphviz-devel
If you install libgraphviz via macports, you may need to add the macports jvm library path via an alias:
:macports {:jvm-opts ["-Djna.library.path=/opt/local/lib"]}
(require '[com.phronemophobic.clj-graphviz :refer [render-graph]])
(render-graph {:edges [["a" "b"]]})
;; writes to graph.png
(render-graph {:edges [["a" "b"]]}
{:filename "my-graph.png"})
See documentation for more info.
dorothy: Hiccup-style generation of Graphviz graphs in Clojure and ClojureScript.
Dorothy works by first generating dot DSL code and then shelling out to the dot command line tool. clj-graphviz works directly with graphviz's underlying c library. The hope is to provide tighter integration with the graphviz library and expose underlying features that are hard to access via the dot command line tool (like graph layout).
Graphviz offers many options to tweak how graphs are rendered. It also offers graph layout without rendering. Exposing more of graphviz's functionality with a friendly clojure interface is a natural next step. Until then, the full graphviz API is available in its form under com.phronemophobic.clj-graphviz.raw.
