Visualise

To visualise metadata, press the 'Tools' button on the start page and select ‘Visualise’. Note that your browser must support WebGL. There are five different visualisation categories:

• basic charts: used for the quantitative representation of data and allow you to represent individual values, compare different values with each other, and highlight differences. They include classic types such as area charts, bar charts, doughnut charts, funnel charts, line charts, line bar charts and pie charts. Choose the appropriate chart type in the bottom right corner.
• timelines: these enable the chronological arrangement and thus structuring of elements. Timelines are used in particular when there are individual events that are clearly separated from one another.
• flow diagrams: these help to clearly present complex processes and procedures involving multiple factors and enable changes in these processes to be highlighted.
• geographic visuals: these are used to present spatial and geographic data as well as relationships. You can create a 3D globe, a worldmap with marked cities or a worldmap with marked countries. They normally require exact geodata.
• networks: these allow relationships and connections between people, objects or abstract entities to be presented. They are especially useful, when showing relative and not absolute positions in these networks.

Choose one of the five categories and you will be forwarded to an input screen. In all five cases you have three sections, where you have to make several decisions. 

• Library: select one or both of the libraries in which you would like to search (Library: all libraries, translation and adaptations, or reception documents)
• 1. Chart: Enter one or more criteria (by pressing `Add Search Criteria´). If you want to compare several criteria in one visualisation, press `Add Dataset/Chart´ (not possible for network visualisations).
• Sort criterion, data format, chart type: depending on the visualisation type, you will find one ore more of these criteria at the bottom of the input mask. 

Select 

1. the category by which your data will be sorted (e.g. title, source or target language, year),
2. the data format (e.g. all data displayed or top 5/10) and
3. the chart type (only for basic charts).

In this example, we have chosen translations into Polish published in 1989 and are looking for the relationship between target language and place of publication. 

To do so, we select 'Metadata' in the 'Search in' field and 'Translations and adaptations' in the 'Library' field. 

Data selection

• In the 'Chart' area, we choose 'Language (target)' and 'is equal' and then select 'Polish'. 

• As a second criterion we choose 'Year - is equal -1989'. 

Chart criteria

We take 'Language (source)' as the 'first criterion' and 'Place' as the 'second criterion'. 

Chart type

Finally we set the 'Initial tree depth' to '2' and choose 'Linear' as the 'Chart type'. 

After pressing the search button, the desired data visualisation appears.

The result is displayed as a line chart. We can see that texts from Polish were translated in 1989 into four different languages (including 'unknown'). 

Interactivity

On the Website, this is an interactive visualisation. Clicking on the circle next to a source language opens it and displays the publication locations.
