Thematic maps are very useful when describing statistical data about places. The data, simply, becomes much easier to understand.
It supports 3 visualizing types:

we are going to build a little chat program that is really easy to get up and running on any server running PHP. No database is required – as the chat will store itself in a simple text file.
The technologies used:
- PHP – Will handle all the server side stuff
- Writing new messages to the text file
- Reading out new messages from the text file
- Retrieving the “state” of the text file
- Basic security
- Periodically asking the server if there are new messages that have been posted
- Appending new messages to the chat
- Scrolling the chat down to the most recent messages
- Asking and setting the user name
- Limiting the text input to prevent gigantic ridiculous messages
- Basic security
It shows examples for most of the functions which gives a strong idea on the coding principles of every framework.
- The Dojo Toolkit
- Adobe Spry
- BBC Glow
- Yahoo UI! Library
According to my web designer experience, one of the most common requests from clients when it comes to WordPress personalization, is to add a basic event calendar to their website.
Finding a good place to position a big table like a calendar within your WordPress template is always a taught work. In addition, the
<table> tag itself is often quite difficult to style in a good way.
One of the calendar solution that I came out with and that I’m particulary proud of is the one I built inside the freshly launched Graham Watson for President website.
One of the most common problems a web developer usually face is related to continuously rotate a fragment of content. It can be a presentation of headlines, small fragments of news or a list of thumbnails. The nature of the thing being rotated doesn’t matter too much here because all those kind of applications share always the same idea: Rotating.
This objective can be achieve in different ways like fading and scrolling. Well here is iCarousel becomes useful. It’s a one step forward trying to generalize all those types of widgets providing a rich presentation and making the task easy to be done.
