Gio.js

English | 中文

Gio.js is an open source library for web 3D globe data visualization built with Three.js. What makes Gio.js different is that it is simple to use Gio.js to customize a 3D data visualization model in a declarative way, add your own data, and integrate it into your own modern web application.

Motivation

This library is inspired by the Arms Trade Visualization project developed by Michael Chang and presented during Google Ideas INFO 2012. See original post. With Gio.js, it is easy to reproduce this fantastic data visualization model, and integrate it into web application.

Simplicity -- Create a 3D global data visualization model with your own data in just four lines of javascript code
Customization -- Design your own globe style with easy to use APIs in Gio.js
Modernization -- Build a responsible, fully interactive, rich 3D frontend application using Gio.js

Getting Started

Installation

Option 1: <script> tag

Include Three.js dependency:

<script src="three.min.js"></script>

Include local Gio.js library

<script src="gio.min.js"></script>

or through CDN

<script src="https://threejs.org/build/three.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/build/gio.min.js"></script>

Option 2: npm

npm install giojs --save

Option 3: yarn

yarn add giojs

Usage

After including "three.min.js" and "gio.min.js" in your html, create a div to render the 3D Gio globe: (the usage of Gio.js is a little bit different in WeChat mini game, checkout this demo to know more about it)

<!DOCTYPE HTML>
<html>
<head>

  <!-- include three.min.js library-->
  <script src="three.min.js"></script>

  <!-- include gio.min.js library-->
  <script src="gio.min.js"></script>

</head>
<body>

  <!-- container to draw 3D Gio globe-->
  <div id="globalArea"></div>

</body>
</html>

To initialize and render the 3D Gio globe:

<script>

    // get the container to hold the IO globe
    var container = document.getElementById( "globalArea" );

    // create controller for the IO globe, input the container as the parameter
    var controller = new GIO.Controller( container );

    /**
    * use addData() API to add the the data to the controller
    * know more about data format, check out documentation about data: http://giojs.org/html/docs/dataIntro.html
    * we provide sample data for test, get sample data from: https://github.com/syt123450/giojs/blob/master/examples/data/sampleData.json
    */
    controller.addData( data );

    // call the init() API to show the IO globe in the browser
    controller.init();

</script>

Gio.js 2.0 Introduction

After Gio.js 1.0 released, developers propose many cool and constructive advise. Gio.js implements most of these features. Gio.js 2.0 comes with many big features such as:

Data group and switchDataSets API to switch between different data sets [introduction]
Provide Three.js programming interface [introduction]
Provide Stats.js programming interface [introduction]
Support export data to continent [introduction]
Provide input data check [issue]
Support WeChat mini program [demo]
New clearData [introduction]
New closeLiveLoader [introduction]
Transparent Background [introduction]
Auto Rotation [introduction]

Examples

Gio.js has many representative demos to show how to work with Gio.js, there are mainly three example resources:

Resource 1: Gio.js Playground

There is a Playground ( playground link ) for developers to play with Gio.js and export Gio.js parameter.

Resource 2: Github "examples" folder

Gio.js has many API demos, and these demos are gathered in examples folder. clone the Gio.js repo, try them in your own environment ~

Resource 3: Live demos on Codepen

Gio.js has a Codepen collection which contains many live demos about Gio.js, click the codepen logo and try to edit them!
