The OECD Flex Viewer - Economic Returns on Education

The OECD Flex Viewer - Economic Returns on Education

This visualization project is built on top of WebGL technology and thus can be best viewed with Google Chrome web browser. For the best performance, Google Chrome is strongly recommended.

Main Focus and Key Features:
The main focus of the project is to not only visualize the data in a given set of data properly but also compare various charts with different parameters at the same time and allow users to dynamically create their own charts. With the OECD Flex Viewer, users can -
- Define and compare multiple charts in a view at the same time. For example, users can compare two charts - one chart of less-educated men data with non-tertiary public education vs. the other chart of more-educated women data with tertiary private education.
- Create and set up their own views, charts, data sources and indicators in addition to the existing choices.
- Define multiple views with various viewing options including Geolocated, Animated, Sort option, Focused chart and Zoom. For example, with the 'Geolocated' checkbox on the View Options panel, users can change the representation of the focused chart - 2D circular-ordered representation of the chart based on the sort option vs. 3D geographical representation of the chart. With the 'Animated' checkbox, users can also make the focused chart travel from the top country to the last one based on the sort option. Please explore other viewing options including Zoom, Particles option, etc.


Demo video: Vimeo: or YouTube:
This video shows a demo of how 'The OECD Flex Viewer' can be used to visualize the 2012 OECD Returns on Education data.

Users may find this video useful if they'd like to know:
- How to use various viewing options.
- How to create a brand new view, chart, data source, and indicator for the purpose of their own visualization.

Chart Reading:
The volume of each sphere, cube or the height of each bar in the charts is all auto-adjusted based on the range of all the values in the selected charts in a given view. With that said, the rates and amounts are handled separately. This means that when users add or remove from the current list of selected charts in the view, the height/volume of each chart bars/spheres/cubes will be rendered based on the new ratios accordingly.

When 'Particles option: Layered' is chosen, the volume of each inner particles sphere represents the OECD average of its corresponding chart to help users easily compare the OECD average of each of multiple charts at the same time. Due to performance concerns, only up to 4 inner spheres - one for the focused chart, one for the chart with the highest OECD average, and two extra charts - can be rendered at one time and each inner sphere consists of 10,000 particle snowflakes.
