4 Open Source Free data visualization JavaScript Library

&http://www.aliyun.com/zixun/aggregation/37954.html ">nbsp; New graphical elements and JavaScript in HTML5 have sparked a revival of interactive data display technologies. Today's browser user interface is not only rich, pleasing, but also as a data visualization carrier, used to display columnar, bubble map and colorful maps.

Interactive data visualization depends largely on the ability of the JavaScript library to work. In this article, we'll look at four JavaScript libraries: D3,infovis,processing.js, and Recline.js. All of these libraries can be used to decorate your Web pages with Dynamic Data visualization, but each uses a different approach to provide this capability. All four are free to use and distribute.

D3

D3 is a wonderful JavaScript based data visualization library that allows you to bind data to the DOM and then apply data-driven transformations to the document. You can use it to create a basic HMTL table with an array, or to use its fluid over and interact to create stunning SVG bars with similar data.

Advantages

Rich examples use standard DOM objects, easy to debug can be extended to create arbitrary data visualization can handle a variety of data formats, including XML, CSV and JSON, etc.

Shortcomings

D3 is very powerful, so it costs more to learn than other libraries D3 is incompatible with earlier versions of IE and requires a deeper understanding of JavaScript

Infovis

Infovis is a JavaScript library that creates interactive data graphs on the web. Infovis is a bit like the Moo tool, a modular object-oriented JavaScript architecture that is typically an intermediary for advanced JavaScript programmers to use. Because it has a modular format, users can use JavaScript Infovis to keep the pages simple. It also includes an animation effect feature, a variety of drawing types, and a class for manipulating JSON data.

Advantages

The

API is easy to understand

Shortcomings

Chart Library is less flexible than other tools to scale easily

處理

Processing.js is a JavaScript library based on the Java graphics system. It not only provides data visualization, but also can realize program image, animation and interactive application.

Advantages

can be used to create animations to a large extent compatible with 處理 Java lightweight, easy to understand mastery

Shortcomings

need to learn 處理 language

Recline.js

Recline.js can help you quickly create data-based applications using JavaScript and HTML. Recline.js has built-in support for loading data from, CSV files, Google Docs, Elasticsearch, Couchdb, and so on. And be able to use tables, maps, timelines and other ways to show the data beautifully. The way you display it can be easily expanded to your own needs.

Advantages

Online practice can be integrated with other JavaScript libraries

Shortcomings

Chart Type Limited
