New feature: Treemap visualization

In order to improve the usability of Openaid.se we have added a new type of visualization on the startpage. Instead of the graph showing the development over time, the default visualization is now a treemap showing the total aid divided by recipient type.

Why a new visualization?

We think that when you look at the total aid for a specific year, it is more relevant to visualize how and where the aid is distributed rather than the changes over time. Partly because inflation and other factors make comparisons of total aid over time less accurate (and the size of Swedish aid is linked to the size of the Swedish GDP). The treemap also brings a nice overview of Swedish aid, which we thought was missing in the previous iteration of the site.

If you instead prefer to see the graph, you can click the graph symbol in the top right corner, and a cookie on your computer will remember your choice. The same logic applies to the map that you see if you click on “countries”/”all countries”, either in the menu or in the corresponding box in the treemap.

Why only on the startpage?

Although technically possible, we don’t consider the treemap useful for all intersections of the data. If the variables are too many or differ greatly in size, that type of visualization becomes cluttered and less useful. In those cases, for example when it comes to distribution between countries or sectors, the bar chart below the graph does the job better. In line with our ambition to keep Openaid.se simple, yet accurate, the treemap is (for now) only available where it makes the most sense – on the startpage.
