From CS 294-10 Visualization Sp10

This visualization allows you to compare the donations of NGOs, corporations, and governments coming out of the top 8 donating countries to Haiti. It allows you to make observations on the relationships between the generosity of these 3 differing types of organizations. It also shows whether funds were committed or uncommitted, meaning they were guaranteed or only promised with no guarantee, respectively.

I chose to represent this as a bar chart because it is easiest to compare a country's donation sources by height, right next to each other. It also allowed a convenient way to distinguish between committed and uncommitted funds, as a stacked bar chart is a familiar way of displaying closely related data (stacked committed/uncommitted) next to differing data (source, country). The scale is in dollars, which serves to help you compare the amount of money each country donated as well. The visualization does not take into account population, so per capita expenditure is obscured. I colored the three sources differently (nominally) because they are the main comparison the visualization wishes you to make, so I thought they should be highlighted and easy to tell apart. I used a lighter color for uncommitted funds since it communicated that they are less substantial than committed funds. An important design decision was to organize the the legend in a hierarchy instead of repeating (eg Corporate Uncommitted, Corporate Committed). I felt this would make it easier to read and pick up on, and for the reader to see that grouped values are closely related, practically the same thing with just a minor difference. I decided not to include the exact dollar amounts for each donation because I felt it detracted from the goal of the visualization, which is to compare the the closely grouped bars against each other. The countries are sorted from highest dollar donations to lowest. This gives the graph an order that makes it clearer since the amounts from the 3 sources cannot be easily combined. I believe it is easy to tell that they're sorted from highest to lowest even though it is not explicitly marked.

I used Excel and a little Photoshop for adjustments.
