The Grapple Notebook REPL

Grapple is a notebook-style REPL for exploring, understanding, and presenting data. It is inspired by the Gorilla REPL and Observables.

Here's an example, a contour plot:

Usage

To run the Grapple server,

lein figwheel

You can also start it from a Clojure REPL. First run,

lein do clean, cljsbuild once prod

Then start a REPL and run,

(require 'grapple.server)
(grapple.server/start-server {})

Besides Clojure primitives, there are currently four built-in components that can be rendered:

grapple.table/matrix, a basic grid of values.
grapple.table/table, a table of values based on a list of maps; headers are the keys of the first map in the sequence.
grapple.plot/scatter, a basic Vega 3 scatter plot.
grapple.plot/contour, a Vega 3 contour plot.
