[JSXGraph][jsxgraph-url] is a JavaScript library that lets you build

2-dimensional scenes full of geometric objects, function curves and interactive

UI elements, potentially with many complex constraints defined between these

objects.



[JSXGraph.cljs][github-url] extends JSXGraph with a [React][react-url] /

[Reagent][reagent-url] component that makes it easy to define JSXGraph

constructions inside of a user interface built with Clojurescript.



## Quickstart



Install `JSXGraph.cljs` into your Clojurescript project using the instructions

at its Clojars page:



[![Clojars Project][clojars]][clojars-url](https://clojars.org/org.mentat/jsxgraph.cljs)



Require `jsxgraph.core` in your namespace:



```clj

(ns my-app

   (:require [jsxgraph.core :as jsx]))

```



Create your first `jsx/JSXGraph` board, populated with two points and an arrow

between them:



```clj

(cljs

 [jsx/JSXGraph {:boundingbox [-3 3 3 -3] :axis true}

  [jsx/Point {:name "A" :size 1 :parents [-1 1]}]

  [jsx/Point {:id "B" :name "BEE!" :size 1 :parents [2 -1]}]

  [jsx/Arrow {:size 4

              :parents ["A" "B"]}]])

```

Here's a more complex example of an interactive vector field, implemented

[here](https://jsxgraph.mentat.org/#Vector%20Field):

See the project's [interactive documentation

notebook](https://jsxgraph.mentat.org) for more guides and examples.



## Canvas Dependency



The [JSXGraph NPM package](https://www.npmjs.com/package/jsxgraph) depends on

the [canvas](https://www.npmjs.com/package/canvas) package.

[canvas](https://www.npmjs.com/package/canvas) comes with many pre-built

binaries, but if you're running on a non-supported OS or processor architecture

NPM may try to compile this dependency from source.



If you run into trouble, [see the `canvas` docs page on

compilation](https://github.com/Automattic/node-canvas#compiling) for

instructions on how to install the dependencies for this process.



## Clerk Support



If you want to use `JSXGraph.cljs` with [Clerk][clerk-url], check out the

[`jsxgraph/clerk` template][jsxgraph-clerk-template-url]. This

[`deps-new`][deps-new-url] template will generate a Clerk project for you, fully

configured to use `JSXGraph.cljs` in your Clerk notebooks.



## Interactive Documentation via Clerk



The project's [interactive documentation](https://jsxgraph.mentat.org) was

generated using Nextjournal's [Clerk][clerk-url]. If

you'd like to edit or play with the documentation, you'll need to install



- [node.js](https://nodejs.org/en/)

- The [clojure command line tool](https://clojure.org/guides/install_clojure)

- [Babashka](https://github.com/babashka/babashka#installation)



Once this is done, run this command:



```sh

bb clerk-watch

```



This will open a browser window to `http://localhost:7777` with the contents of

the documentation notebook. Any edits you make to `dev/jsxgraph/notebook.clj` will

be picked up and displayed in the browser on save.
