Questions = Answers(or at least clues to how to visualize)
• What Kind of Question Am I Asking?
• Statistical Analysis/Profiling
• When? = Temporal
• Where? = Geospatial
• What? = Topical
• With Whom? = Network

Just as in Story, Data is is Best Understood within Context
• Use a Key / Legend
• Decode what You Encoded
• Give Context
• Tell Level of Data, if not obvious
• Show Time Frame
• Region / Coverage Area
• Kind of Topic

Visualization Types (Reference Systems)
1. Charts: No reference system—e.g., Wordle.com, pie charts2. Tables: Categorical axes that can be selected, reordered; cells can be color coded and might contain proportional symbols. Special kind of graph.3. Graphs: Quantitative or qualitative (categorical) axes. Timelines, bar graphs, scatter plots.4. Geospatial maps: Use latitude and longitude reference system. World or city maps.5. Network graphs: Node position might depends on node attributes or node similarity. Tree graphs: hierarchies, taxonomies, genealogies. Networks: social networks, migration flows.
