Data Visualiza0on

Mul0ple Approaches


Why Visualize Data?

•  Spreadsheets are great… but it’s difficult to understand with large datasets

•  Examine Concepts from mul0ple perspec0ve – Spa0al – Temporal

•  Integrate data from mul0ple sources •  Ex. Fault lines, earthquakes, and popula0on data

•  Interac0ve ≠ expensive or difficult
