Student flows in the Dutch education system

For the Dutch Ministry of Education, Culture and Science we visualized flows of students in the Dutch post-secondary vocational education system. It uses interactive Sankey diagrams to show the more than 40.000 possible data flows in a privacy-safe way. The user can view the huge dataset from multiple perspectives, per region, per school, or per type of flow and per year.

Hierarchical data components

Many data are either hierarchical by nature or better to understand by grouping it to one or multiple variables. We created generic components for viewing such data, such as an interactive treemap, circle diagrams, scatterplots and hierarchical bar charts. Click on the pictures on the right to go to the respective interactive visualisation and change grouping, color or other variables to explore the data.

We use these components to visualize metadata in our data consultancy projects, but we also provide them for free on our site to be used by others. Feel free to upload your own data (csv) and play with it. The data stays in your browsere and are not uploaded to our server to it's safe. Note that dedicated versions of these software can be created on request.

Internet population

Based on global indicators from the UNSD we calculated the number of internet users per country from 1990 to 2005.

Using the interactive legenda you can play with the data per continent.
