Interactive arts and charts visualizations with Clojure(Script), Vega-lite, and Vega. Flower viewing 花見 (hanami)
Hanami is a Clojure(Script) library and framework for creating interactive visualization applications based in Vega-Lite (VGL) and/or Vega (VG) specifications. These specifications are declarative and completely specified by data (JSON maps). VGL compiles into the lower level grammar of VG which in turn compiles to a runtime format utilizting lower level runtime environments such as D3, HTML5 Canvas, and WebGL. In addition to VGL and VG, Hanami is built on top of Reagent and Re-Com.
