BirdEye – Declarative Visual Analytics Library

Posted · Category: Charts, MIT License

BirdEye is the Declarative Visual Analytics Library. It is a community project to advance the design and development of a comprehensive open source information visualization and visual analytics library for Adobe Flex. The actionscript-based library enables users to create multi-dimensional data visualization interfaces for the analysis and presentation of information.

DVAL is a XML-based syntax language for specifying visual representations. The approach is based on the concepts of Leland Wilkinson’s book The Grammar of Graphics. In this book he describes a foundation for producing a comprehensive information visualization language. The advantage of the DVAL is that all visuals are created using the same structure and logic.

Visually Connect Elements on Web Page like Yahoo! Pipes

Posted · Category: Charts, MIT License

jsPlumb jQuery plugin provides a means for a developer to visually connect elements on their web page, in much the same way you might have seen on Yahoo Pipes. jsPlumb allows you to connect elements on the screen with “plumbing”, using a Canvas element when supported, and Google’s ExplorerCanvas script to support older browsers. Full transparent support for jQuery dragging is included, the API is super simple, and the compressed version of the script is just 10.5K.

It relies on jQuery 1.3.x or jQuery 1.4.x (tested on 1.3.2 and 1.4.2), and also jQuery UI 1.7.2 (if you want to support dragging). For Canvas support in IE you also need to include Google’s ExplorerCanvas script.


Requirements: jQuery Framework

Grafico – Charting Library Built with Raphaël and Prototype

Posted · Category: Charts, MIT License

Grafico is a javascript charting library built with Raphaël and Prototype.js. The library provides a wide array of graphs and stays with the guidelines laid out by Stephen Few and Edward Tufte. Grafico provides pretty charts that effectively communicate their information.

This means you get awesome graphs such as stacked area charts and sparklines, but no pie charts or bar charts with every bar a different color. Each graph type has numerous API options to customize it’s look and behavior. Some highlights: pop-up hovers, meanlines and watermarks. Minified, Grafico is about 30kb and available under the MIT license.

Produce Interactive Charts of Time Series with dygraphs

Posted · Category: Charts, License Free

dygraphs is an open source JavaScript library that produces produces interactive, zoomable charts of time series. It is designed to display dense data sets and enable users to explore and interpret them. You can mouse over to highlight individual values. Click and drag to zoom. Double-click to zoom back out. Change the number and hit enter to adjust the averaging period.

Another significant feature of the dygraphs library is the ability to display error bars around data series. dygraphs is purely client-side JavaScript. It does not send your data to any servers – the data is processed entirely in the client’s browser.


Requirements: JavaScript Enabled

New Interactive Charting Library in Pure Javascript

Posted · Category: CC License, Charts

Highcharts JS is a charting library written in pure JavaScript, offering an easy way of adding interactive charts to your web site or web application. Highcharts JS currently supports line, spline, area, areaspline, column, bar, pie and scatter chart types.

It works in all modern browsers including the iPhone and Internet Explorer from version 6. Setting the Highcharts configuration options requires no special programming skills. The options are given in a JavaScript object notation structure, which is basically a set of keys and values connected by colons, separated by commas and grouped by curly brackets.

On hovering the chart, Highcharts JS can display a tooltip text with information on each point and series. By zooming in on a chart you can examine an especially interesting part of the data more closely. Zooming can be in the X or Y dimension, or both.

Create Charts & Graphs from Tables using HTML 5 Canvas

Posted · Category: Charts, GPL License, MIT License

Filament Group wrote an article describing how to use JavaScript to scrape data from an HTML table and generate charts using the HTML 5 Canvas element. The technique is particularly useful because the data for the visualization already exists in the page in structured tabular format, making it accessible to people who browse the web with a screen reader or other assistive technology.

Now they have rewritten and extended the code behind the technique and packaged it up as a new jQuery plugin called “Visualize“, which you can download. The plugin provides a simple method for generating bar, line, area, and pie charts from an HTML table, and allows you to configure them in a variety of ways.

jQuery Visualize Plugin

Requirements: IE6, IE7, IE8, Firefox 2, Firefox 3.5, Safari 3 and 4, Opera 9

Axiis is an open source data visualization framework designed for beginner and expert developers alike. Axiis gives developers the ability to expressively define their data visualizations through concise and intuitive markup.

Axiis provides both pre-built visualization components as well as abstract layout patterns and rendering classes that allow you to create your own unique visualizations. Axiis was designed to be a granular framework, allowing developers to mix and match components and build complex output by compositing together basic building blocks.

Protovis – Visualization Toolkit for Javascript using Canvas

Posted · Category: BSD License, Charts

Protovis is a visualization toolkit for JavaScript using the canvas element. It takes a graphical approach to data visualization, composing custom views of data with simple graphical primitives like bars and dots. These primitives are called marks, and each mark encodes data visually through dynamic properties such as color and position. Although marks are simple by themselves, you can combine them in interesting ways to make rich, interactive visualizations.

To facilitate this, Protovis supports panels and inheritance. A panel is a container for marks; the contained marks are replicated for each data point on the panel. You can vary the panel position to create small multiple displays, or you can overlay panels. Inheritance lets you derive new marks from existing ones, while sharing some or all of the same properties. This is the same principle as cascading in CSS, or prototypal inheritance in JavaScript.

Please note: Protovis is in its early stages of development. At the moment, they only support Firefox 3, but they plan on adding support for Chrome and Safari 4.


Requirements: Firefox 3
