About

Declarative, functional & multi-format data visualization toolkit based around @thi.ng/hiccup.

This package largely started as a port of the visualization module of the
Clojure version thi.ng/geom-clj and is still
undergoing major redesigns.

For reference & what to expect (links to the Clojure version):
