RESEARCH QUESTIONS

How does GNI, Health expenditure and Life expectancy of different countries change over time since 1995 to 2010?

Would these growth mentioned above be various among different countries?

What’s the correlation between GNI & Health expenditure, GNI & Life expectancy, as well as Health expenditure & Life expectancy?

We also would like to compare these correlation mentioned above among different countries.

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

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

SYSTEM DESCRIPTION EVALUATION

Participants felt a little confused about the missing data on the geographical map.

Bubbles are too crowded on the relevance chart.

It needs to clearly identify the colors meaning in both geographical map and relevance chart.

No highlight of countries on the geographic map when users clicked on the bubbles.
