A visualization combining all data from OECD tables 9.1, 9.2, 9.3, 9.4 in their 2012 education at a glance report.

Visualization method aimed to combine all the data in a way that promotes visual differentiation that might uncover any trends or patterns while still allowing relative quantitative comparisons to be made.

Each bird/bow-tie/flying-fish represents a cluster of public and private investment and outcome into one sector of education. From left to right, costs, benefits, and then net totals are represented with "private" values represented as the top half and "public" values represented in the reflected lower half.

The "bow-tie" was chosen to inherently convey the feeling of what is put into education, and then what comes out. Combined with the selected colour coding, the flow of any "exchange" between the private and public sector can also be examined.

The overall goal would be to use this representations to discover possible patterns or areas of interest to further delve into the data, and ideally help uncover any trends that contribute to the successful and overall beneficial, investment in education.

(the method also has the ability to transfer onto other tables in the OECD report to explore for any related trends, but given that there was not enough time to even fully label or refine this layout, that will just have to wait until next time)
