Package Exports

@tensorflow/tfjs-vis

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@tensorflow/tfjs-vis) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

tfjs-vis

tfjs-vis is a small library for in browser visualization intended for use with TensorFlow.js.

Its main features are:

A set of visualizations useful for visualizing model behaviour
A set of high level functions for visualizing objects specific to TensorFlow.js
A way to organize visualizations (the visor) of model behaviour that won't interfere with your web application

The library also aims to be flexible and make it easy for you to incorporate custom visualizations using tools of your choosing, such as d3, Chart.js or plotly.js.

Installation

You can install this using npm with

npm install @tensorflow/tfjs-vis

or using yarn with

yarn add @tensorflow/tfjs-vis

You can also load it via script tag using the following tag, however you need to have TensorFlow.js also loaded on the page to work. Including both is shown below.

<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs"> </script>
<script src="https://cdn.jsdelivr.net/npm/@tensorflow/tfjs-vis"></script>

API

See https://js.tensorflow.org/api_vis/latest/ for interactive API documentation.

Sample Usage

const data = [
  { index: 0, value: 50 },
  { index: 1, value: 100 },
  { index: 2, value: 150 },
];

// Get a surface
const surface = tfvis.visor().surface({ name: 'Barchart', tab: 'Charts' });

// Render a barchart on that surface
tfvis.render.barchart(surface, data, {});

Building from source

To build the library, you need to have node.js installed. We use yarn instead of npm but you can use either.

First install dependencies with

yarn

npm install

Then do a build with

yarn build

npm run build

This should produce a tfjs-vis.umd.min.js file in the dist folder that you can use.
