clj-wordcloud

A simple clojure wrapper around kumo to generate wordcloud

Leiningen

[xtreak/clj-wordcloud "0.0.1"]

Example

Given a map of element and the frequency the following image is generated. More examples/examples.clj.

TODO

API parity with Kumo
clojure.spec for docs and validation
Cool examples
Better tests

Contributing

Contributions are welcome. Please refer to CONTRIBUTING.md.

Stability

This library is still in early development phase and the API is subject to change. API design comments are welcome.

Thanks

Thanks to @kennycason for kumo without which this library is not possible
