Prototype makes it easy for developers to work with HTML forms, asynchronous Ajax requests, and create and manipulate HTML elements. However, Prototype is a bare-bones library, providing none of the widgets or special effects that are included in many competing open-source JavaScript libraries, such as Dojo and YUI. It should not come as a surprise, then, to find that developers have stepped in to fill this void, creating a number of libraries that sit on top of Prototype and/or Script.aculo.us. There are several libraries that make it possible to draw graphs and charts within the browser window using JavaScript; this week, Deensoft announced the pending availability of their graphing library for Prototype, known as ProtoChart.
