Refelection on Reading:
According to Bederson & Shneiderman (2003), information visulization is a research aiming at supporting discovery and analysis of data through visual exporation. Nowadays, Interative techniques are capable of handling a million items effectively visible and manageable on screen. For example:

1. Hardware acceleration: achieve the speed required for interation and animation.

2. Non-standard visual attributes: synthetic overlap count to enhance visulization.

3. Animation and interaction: using time multiplexing techniques to analyze the data across several views.

4. Applied techniques to treemaps and scatter plots.

5. Other techniques: Image Library, drag and drop strategy for labelling photos, extensible zoomable user interface graphics toolkit in Java, a hierarchical multi window world wide web browser, photofinder web, and zoomable user interfaces.
