Announcing C2, a data visualization library inspired by D3.js
C2 is not a charting library; there are no plotting functions like
"scatterplot" or "piechart" .
Instead, C2 is a collection of scales, map projections, and component
templates (e.g., axes) that you can compose to build custom data
graphics on a DOM (e.g., HTML or SVG).
C2 is written in Clojure and can be used on the JVM in conjunction
with the Hiccup HTML rendering library to generate markup.
C2 can also be used within ClojureScript, where it includes
+ its own Hiccup compiler that acts directly on live DOM nodes
+ event wrappers for use with large datasets (via delegation)
+ DOM manipulation helpers (the usual suspects for manipulating
styles/attributes, selecting, appending, and removing DOM nodes)
To get started, just add it to your project.clj:
[com.keminglabs/c2 "0.1.0"]
There is also a standalone uberjar with built-in web server if you
don't have Leiningen around; see this 2-minute screencast:

Some projects that pair well with C2:
cljx, a Leiningen plugin that statically rewrites metadata-annotated
Clojure code into platform specific code:
https://github.com/lynaghk/cljx
Cassowary, a linear constraint solver accessible from ClojureScript:

Vomnibus, a collection of geographic data and color schemes:
