Examples

On this page we will describe a set of examples that showcases the features of CubeViz. The Dataset we used is the RDF version of the Digital Agenda Scoreboard (DAS), that was published within an own Web Application. The DAS Web Application was created especially for presenting specific scenarios such as :

  1. Analysis of one indicator and compare countries
  2. The evolution of an indicator
  3. Comparison of two indicators
  4. A Country profile
Note that CubeViz is a generic application for statistics from widespread domains and is not adopted for specific use cases. Because of that, users have more options to configure a desired chart output which is indeed in some cases not as comfortable as the Digital Agenda Scoreboard.

Structure of this page:

Example 1: Analysis of the Total Fixed Broadband Coverage for 2010

The first example is about the analysis of a specific indicator of the DAS dataset. To get the result illustrated in the depictions Fig.1 and Fig.2 proceed with the following actions.

Creation of the chart output with DAS:

  1. First start the DAS Web Application: Open DAS - Scenario 1
  2. Select the Indicator: Total Fixed Broadband Coverage of Indicatorgroup Broadband in the respective selection box.
  3. Select the Year 2010 in the respective selection box.
  4. Select all countries in the Country selector (per default all of them should still be selected)
The output should be somehow the same as depicted in Fig.2. If you do not want to follow these steps you can click here to jump directly to the output.

In difference to the workflow in the Digital Agenda Scoreboard you can produce a similar output with CubeViz as follows:

  1. Start CubeViz as part of the Data Portal for the European Commission with the DAS DataCube: Start CubeViz with DAS DataCube
  2. Select on the left side the Data Structure per Indicator.
  3. Select the dataset Total fixed broadband coverage (supply as a % of total population).
  4. Select all elements of the dimension Country (click on the icon behind the dimension).
  5. Select only the element 2010 of the dimension Year (click the Icon behind the Dimension).
  6. Click on Update Visualization
  7. The first renderd Chart is a Bar chart. To get a chart similar as the one in Digital Agenda Scoreboard click on the upper right corner on the icon for the Column chart.
As you can see both visualizations and the workflows to produce them are similar.

Example 2: The Evolution of households with access to the Internet at home

This example is about the evolution of a specific indicator over time. In order to keep it simple we will observe only 3 countries and compare them with the average over the European Union 27 countries.

Creation of the chart output with DAS:

  1. First start the DAS Web Application: Open DAS - Scenario 2
  2. Select the indicator Households with access to the Internet at home of indicatorgroup Internet usage in the respective selection box.
  3. Select the countries Belgium, European Union - 27 countries, France and Germany in the country selector (by default the European Union - 27 countries should still be selected).
If you do not want to follow these steps you can click here to jump directly to the output. The result of this selection leads to a line-chart containing 4 lines representing the countries. The temporal dimension is represented on the X-Axis, and the percentage values are put on the Y-Axis (compare with Figure 4).

A similar output can be created with CubeViz:

  1. Start CubeViz as part of the Data Portal for the European Commission with the DAS DataCube: Start CubeViz with DAS DataCube
  2. Select on the left side the Data Structure per Indicator
  3. Select the Dataset % of Housholds with Access to the Internet at home
  4. Select the elements Belgium, European Union - 27 countries, France and Germany of the dimension Country (click the Icon behind the dimension)
  5. Select all elements of the dimension Year. (click on the icon behind the dimension)
  6. Click on Update Visualization
  7. The first rendered Chart is a bar-chart. To get a similar chart click on the top-right corner on the icon for the line-chart.
  8. Click again on the line-chart icon to open the options dialogue and configure there the type spline (and a switch of the axes if necessary)

The result with CubeViz is quite similar to the output of DAS (compare Figure 3 and 4). In DAS the years are limited from 2004 until 2012, which can not be configured. For France, data is missing for the Year 2005, which can be seen in both tools, but with different visualized elements. Try out the Column and Polar charts with the same selection.
