Hanami
Hanami provides interactive plotting and charting with ClojureScript and Vega.
About Hanami
Hanami is a Clojure(Script) library and framework for building interactive visualization applications. It creates charts and plots from Vega-Lite and Vega specifications, which are declarative and defined entirely by data as JSON maps. Vega-Lite compiles into Vega, which compiles to a runtime that uses lower-level environments such as D3, HTML5 Canvas, and WebGL. Hanami is built on Reagent and Re-Com.
Instead of a conventional API for generating specifications, Hanami uses parameterized templates with recursive transformations. Templates can be composed, merged, and shared as libraries of reusable plots and visualizations. Hanami itself includes only a small set of very generic templates, so domain- or task-specific templates are expected to be built by users or other libraries.
Key features
- Creates interactive visualizations from Vega-Lite and Vega declarative specifications
- Parameterized templates with recursive transformations
- User-definable templates with their own defaults
- Tabbing system for named visualization groupings
- Multiple simultaneous independent or dependent visualizations per grouping
- Automatic grid layout and an option system for customization
Best for: Developers who work in Clojure or ClojureScript and want to build interactive charts and visualization applications from reusable templates.
Good for
- Specifications are declarative JSON maps, defined entirely by data
- Templates can be shared as reusable libraries of plots and visualizations
