jQuery is a fast, small, and feature-rich JavaScript library. It makes things like HTML document traversal and manipulation, event handling, animation, and Ajax much simpler with an easy-to-use API that works across a multitude of browsers. With a combination of versatility and extensibility, jQuery has changed the way that millions of people write JavaScript.

  This jQuery plugin makes simple clientside form validation easy, whilst still offering plenty of customization options. It makes a good choice if you’re building something new from scratch, but also when you’re trying to integrate something into an existing application with lots of existing markup. The plugin comes bundled with a useful set of validation methods, including URL and email validation, while providing an API to write your own methods. All bundled methods come with default error messages in english and translations into 37 other languages.

  SVG (Scalable Vector Graphics) is a "modularized language for describing two-dimensional vector and mixed vector/raster graphics in XML". It is a W3C Recommendation currently at version 1.1.

  "SVG is a language for describing two-dimensional graphics in XML. SVG allows for three types of graphic objects: vector graphic shapes (e.g., paths consisting of straight lines and curves), images and text. Graphical objects can be grouped, styled, transformed and composited into previously rendered objects. The feature set includes nested transformations, clipping paths, alpha masks, filter effects and template objects."

  SVG is implemented in Firefox natively from version 1.5, Opera natively from version 8.5, Safari natively from version 3.0, and in IE from Windows 98 onwards via the Adobe SVG viewer or the Renesis Player. Not every SVG construct is supported by these implementations.

  This plugin allows you to manipulate the SVG from JavaScript. For more details see the reference documentation, or the graphing reference or plotting reference pages.

  The Google Map version 3 plugin for jQuery and jQM takes away some of the head aches from working with the Google Map API. Instead of having to use Google event listeners for simple events like click, you can use jQuery click events on the map and markers.
