From CS 294-10 Visualization Sp10

Looking at the data, I thought about where these countries are located relative to Haiti. Who are the people that care and who is giving aid to Haiti? I chose to go with a map because it helps to give a spatial understanding the relationship between countries and Haiti.

I approached my design by first coming up with a pie graph to view the different donors as a whole, to see who gives the most money to Haiti. Then I mapped each of the colors from the pie graph to countries on the map. Each country was linked to Haiti with an arrow with a thickness that indicates the amount of donation that it gives. Also, each country is colored and each country's arrow is colored, to help understand where the donations are coming from.

I thought it was really interesting to see where the majority of donations came from seemed to be in relative proximity to one another, and it seems as though you could make some sort of connection between countries and their level of altruism. Notably, the U.S. and Canada were by far the largest donors, while the European nations were also major contributors. Interestingly, Spain came out to be the highest of the European countries and was the closest of the countries to Haiti. Brazil and Guyana were contributors to Haiti as well, being close to Haiti, but generally many of the South American countries did not contribute.

There are undoubtedly many flaws with this design. First is that the lines on the visualization can be unwieldy and hard to comprehend, as well as the fact that they can cover up other countries. Secondly, if I had more time, I would have placed Haiti at the very center of the map rather than use a standard map, so that the relationship of Haiti to countries like Australia, China, and Japan would not appear as distorted. Lastly, it would have been helpful to also label the countries rather than show just graphics. Another limitation is that the lines cannot show scale very well in their thickness, so it is hard to compare donations between two countries, especially if they are close to each other.
