About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Plotting.
To use in Observable,
plot = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/plot@umd/browser.js' )The previous example will load the latest bundled code from the umd branch. Alternatively, you may load a specific version by loading the file from one of the tagged bundles. For example,
plot = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/plot@v0.3.1-umd/browser.js' )To vendor stdlib functionality and avoid installing dependency trees for Node.js, you can use the UMD server build:
var plot = require( 'path/to/vendor/umd/plot/index.js' )To include the bundle in a webpage,
<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/stdlib-js/plot@umd/browser.js"></script>If no recognized module system is present, access bundle contents via the global scope:
<script type="text/javascript">
(function () {
window.plot;
})();
</script>Plot API.
