  3. 3. RESEARCH QUESTIONSQ1 How does GNI, Health expenditure and Life expectancy of different countries change over time since 1995 to 2010? - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Q2 Would these growth mentioned above be various among different countries? - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - What’s the correlation between GNI & HealthQ3 expenditure, GNI & Life expectancy, as well as Health expenditure & Life expectancy? - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Q4 We also would like to compare these correlation mentioned above among different countries.

  6. 6. DESIGN PROCESS (1/2)● Data processing ○ Raw data sets in CSV formats --> implemented a parser in python that parsed all the data into JSON format --> three files after data organization - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -● Design criterias ○ Enable to compare several countries in a one view ○ Enable to display trends overtime ○ Enable to display the correlation between two factors ○ Enable to explore hidden countries
  7. 7. DESIGN PROCESS (2/2)Design Decisions● Thematic Map ○ To show a particular theme connected with a specific geographic area. ○ Zoom control for global view & details ○ Mouse hover for tooltip popping out● Relevance Map ○ x-axis and y-axis individually represent two indicators ○ Each bubble represents a country: colors to code continent and size to code its population. ○ Default view of continent bubble to spread out ○ Transparent color avoiding interlacing● Filters
