Motivation
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.
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/giojs@2.2.1/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!
