1. POPULAR DATA VISUALIZATION BASED ON VISION OF HANS ROSLING
2. FACT-BASED WORLD Data is everywhere around us, but they are noisy hypes and anomalies inaccurate data incomplete data irrelevant data noise – opposite of information
3. FACT-BASED WORLD Data is everywhere around us, but they are in complex format many formats xls / csv / xlsx / rtf / xml / json / unstructured preprocessing needed cleaning, normalization, transformation, feature extraction understanding data mining, machine learning
4. FACT-BASED WORLD Data is everywhere around us, but they doesn’t make sense wrong algorithms used wrong correlations presumed cannot uncover meaning
5. FACT-BASED WORLD Data is everywhere around us, and they are accessible Open data idea that certain data should be freely available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control.

7. FACT-BASED WORLD Data is everywhere around us, and we have media to share
8. GOAL See world in perspective Use statistics to test hypothesises Fit a statistical model and predict future Make sense of data and understand life and universe
9. GOAL Features Measures Methods Mean Density Distribution Error Deviation Confidence Algebra Learning mechanisms Analysis methods Clustering methods Model fitting Interpolations Life expectancy Economy Society Education Environment Energy Health Infrastructure Work Educate people in statistics and relevant tools
10. GOAL Present data using visualisation to tell the story immediately and make it mpossible to ignore
11. ULTIMATE GOAL Improve health Help developing countries Stabilize economics Improve mainstream education Find most efficient solutions Use produced information for our benefit and use it when planning
12. TOOLS Use power of modern technologies to enable people to use statistics as easy as shopping at Amazon
