The document discusses different types of metadata visualization including visual metadata, textual metadata, and combinations of visual and textual metadata. It notes that visual metadata representation should provide sufficient detail while avoiding deception, and that textual metadata used to identify entities should include the most important information elements in a sensible order.

2. Information Visualization
• Some Areas
– Textual information
– Temporal data
– Spatial Data
– Spatio-temporal data
– Numeric Data
– Graph
– And even more…

3. Remember
• Information Visualization is not UI Design
• Information Visualization at the concerns also
– Information representation
– Navigation through information space
