In general, gauges are built with Flash as they require an animation.

Rather than Flash gauges, this is a pure JavaScript & canvas gauge.

How it works?

The code sets a starting and an end value. Using the HTML Canvas element, it draws the needle and simply rotates it according to the current data. For more information about Canvas element, check this WRD post.

As Internet Explorer does not support Canvas element natively, this Canvas gauge uses IECanvas for that.

Working demo can be found here.

Tip:

There is also a dynamic Flash gauge at the same page.

fgCharting is a jQuery plugin which helps us to create accessible charts from standard table data with canvas.

Using this chart plugin, we can create several types of graphs, such as pie, line, area, and bar.

As canvas is not supported by default in Intenet Explorer, you can use ExplorerCanvas to add this functionality to it (WRD post for more details).

Visifire is a set of open source Microsoft Silverlight chart components.

Visifire lets you create stunning charts with ASP, ASP.Net, PHP, JSP, ColdFusion, Ruby on Rails or just simple HTML in minutes.

MooWheel is a mootools based script which visualizes data and connections between items like a wheel.

MooWheel uses CanvasText and ExCanvas libraries other than mootools which are already included in the package.

Usage of this data visualization script is pretty simple. You simply create a data array, add a canvas tag and call the function.

There is a very nice demo here.

CSS Globe has a chic animated progress bar built with CSS and an animated GIF file.

It is simply an EM tag above an animated GIF file which is blocking the part of the GIF file to creating the progress bar stop effect.

As this progress bar is only a visual trick, it can not show a "live" progress but only a static one which the percentage of progress to be shown was defined before the page is loaded.

Smoot is a tool, developed with xajax and Pear::DB for creating diagrams of icons and links between them.

Features include Google Maps and Google Earth integration, configurable tool palettes, and automated palette generation from a Google local query.

Smoot builds relations between objects with mouse clicks and the result can be stored easily. This nice tool can be a starting or an inspiration point for many projects like "online heritage services", "online diagram services" and much more.
