Hello everyone. I'm excited to announce that this weekend I released version 1.4.0 of Oz, a library for working with Vega & Vega-Lite visualizations from Clojure. This release comes a bunch of nice changes: • Various Vega (js) libs are now up to date • The publish! (plot sharing) functionality, which broke when GitHub removed support for anonymous gists, has now been fixed; It is now possible to specify credentials so that gists will be associated with your GitHub account. • The Reagent API is now in a separate namespace from the socket/figwheel machinery which Oz depends upon for it's REPL/JVM based plotting functionality, solving a mess of error messages when attempting to use it as such • If you forget to call start-plot-server!, it now gets called for you on your first call to v! or view! • Some dependencies have been updated, resolving an issue with Oz being used under JVM 9 and 10 • Improved styling Please check it out here: https://github.com/metasoarous/oz

I'm also happy to announce the launch of http://ozviz.io, a tool for sharing scientific documents written in the same combination of hiccup and Vega/Vega-Lite which the view! function accepts. The old (and now deprecated) publish-plot! function would only work with pure/single Vega or Vega-Lite plots, as this functionality was predicated on the IDL's fabulous (but hiccup ignorant) Vega Editor. Now, when you call the more general publish! function with hiccup input, an http://ozviz.io url is printed out, which when followed, will load the corresponding hiccup+vega document from the generated gist. This facilitates the sharing/publishing of more involved scientific documents, and for folks who hate to leave the comfort of their favorite text editor, poses a nice (and in some ways more flexible) alternative to the standard scientific notebook environment. If this sounds interesting, please take a peek and let me know what you think 🙂 Thanks!
