Dojo is an Open Source DHTML toolkit written in JavaScript. It builds on several contributed code bases (nWidgets, Burstlib, f(m)), which is why we refer to it sometimes as a “unified” toolkit. Dojo aims to solve some long-standing historical problems with DHTML which prevented mass adoption of dynamic web application development.

Dojo allows you to easily build dynamic capabilities into web pages and any other environment that supports JavaScript sanely. You can use the components that Dojo provides to make your web sites more usable, responsive, and functional. With Dojo you can build degradable user interfaces more easily, prototype interactive widgets quickly, and animate transitions. You can use the lower-level APIs and compatibility layers from Dojo to write portable JavaScript and simplify complex scripts. Dojo’s event system, I/O APIs, and generic language enhancement form the basis of a powerful programming environment. You can use the Dojo build tools to write command-line unit-tests for your JavaScript code. The Dojo build process helps you optimize your JavaScript for deployment by grouping sets of files together and reuse those groups through “profiles”.

Open Flash Chart

Open Flash Chart 1.x was great and it works like a dream. But I made some little mistakes which over time grew and anyoyed me and made the source code weird. So I decided it was time to re-jigger the code and make it pretty again. The big change is moving the data format to JSON. This has made a big difference and has allowed some pretty cool new features.

Why choose Open Flash Chart?

This is a little gentle propaganda for the project. Like all opinions, disregard it and make up your own mind.

Edge cases such as

• tooltips encourage user interactivity and data exploration
• what happens to the tooltip when two points are in the same position?
• you can re-size the charts
• missing data
• save the chart as an image
• You can highlight or emphasize one (or many) points
