- 7. Modern equivalent of Visual Communication • Communicate information clearly and efficiently to users via descriptive statistics • Make complex data more accessible, understandable and usable • Help users analyze and reason about data, evidence, causality, and relationships 7 Need for Data Visualization
- 9. We understand better with pictures Humans assimilate information better 9 A Picture is worth a 1000 words
- 11. Story The Right Questions Context Roles Visual Representation 11 Show and Tell
- 12. 12 Show relationships of data points. More used for scientific and exploratory uses Not very useful for business cases. Scatter plots
- 13. 13 Scatter Plots
- 14. Bar Charts are common and versatile charts used for comparison. Useful because they are so common and information is absorbed quickly. 14 Bar Charts
- 15. Useful for visualizing numbers of different magnitudes and trend analysis. 15 Area Graphs
- 16. Plot continuous data, often over time. 16 Line Graphs
- 17. Communicating one or two pieces of information 17 Simple Text 80%of the folks here are reading this slide now
- 18. 18 Tables Can communicate different information to different audiences • Useful when you have mixed units of measure
- 19. 19 Visualize Data from a table Color will focus attention Better Visual Cues Better perception of tabular data Heat Map
