JS Charts is a free JavaScript based chart generator that requires little or no coding. With JS Charts drawing charts is a simple and easy task, since you only have to use client-side scripting (i.e. performed by your web browser). No additional plugins or server modules are required. Just include our scripts, prepare your chart data in XML or JavaScript Array and your chart is ready!

JS Charts lets you create charts in different templates like bar charts, pie charts or simple line graphs.

pChart is a PHP class oriented framework designed to create aliased charts. Most of todays chart libraries have a cost, our project is intended to be free. Data can be retrieved from SQL queries, CSV files, or manually provided. This project is still under development and new features or fix are made every week.

Focus has been put on rendering quality introducing an aliasing algorithm to draw eye candy graphics. Rendering speed has been dramatically enhanced since the first version, we’ll still continue optimising the code

JFreeChart is a free 100% Java chart library that makes it easy for developers to display professional quality charts in their applications. JFreeChart’s extensive feature set includes:

• a consistent and well-documented API, supporting a wide range of chart types;
• a flexible design that is easy to extend, and targets both server-side and client-side applications;
• support for many output types, including Swing components, image files (including PNG and JPEG), and vector graphics file formats (including PDF, EPS and SVG);
• JFreeChart is “open source” or, more specifically, free software. It is distributed under the terms of the GNU Lesser General Public Licence (LGPL), which permits use in proprietary applications.

The JFreeChart project was founded eight years ago, in February 2000, by David Gilbert. Today, JFreeChart is used by approximately 40,000 to 50,000 developers (see a list of some of the products and projects that use JFreeChart). The project continues to be managed by Mr Gilbert, with contributions from a diverse community of developers. If you are interested in joining the project, please see the Developers page.

Data visualization is mostly achieved with flash applications or with help of some programming languages. Are those solutions the only way to present, let’s say simple data chart? How about giving it a try with nothing but good ol’ css?
