Environment Visualizations (E.V.)

Team: Cathy Cao, Kristi Gable, Shawn Kang

Problem and Motivation: As countries are becoming more developed, the level of income influences its ability to preserve the environment and guides the choices in treatment. Environment preservation is gaining substantive worldwide attention, so we want to explore how level of income impacts treatment of the environment. Our visualizations help people see the trends in the output of countries in different income groups to the environment. Our hope is that after exploring our visualizations, people can see how we, as a world, affect the environment as countries develop over time.

Approach: We used data on the environment from the World Bank to create three visualizations: a map, a line graph with accompanying donut charts, and a stacked bar graph. The map is best for worldwide comparisons for environmental indicators. The line graph and donuts show trends of indicators over time for income groups and indicators' subcategories. The stacked bar graph presents how different subcategories contribute to a larger category for one specific income group. These visualizations help accomplish the goal of showing environmental indicator intensities via the map, partition the data into subcategories per income group, show the change in trends over time, and make side-by-side comparisons among all income groups.

Navigation Tips:

Map:

roll your mouse over a country to see the name
select "High", "Upper-Middle", "Lower-Middle", and "Lower" checkboxes to see or hide income groups
drag the selector on the timeline to see changes over time or a different year

Line Graph:

click a point on the graph to see further breakdowns via donut charts
toggle the top control to see a stacked bar graph

Stacked Bar Graph:

change to the "grouped" layout to see subcategory trends
select one income group: "High", "Upper-Middle", "Lower-Middle", and "Lower"
toggle the top control to see a line graph
