Image Download: Single Chart

[KerstinFaye]

Is your feature request related to a problem? Please describe.
As a user I would like the possibility to download the visualization as an image. Users want to be able to use the visualizations in reports as a static version. They must be able to permanently display labels and data sources and export an image (PNG)

Describe the solution you'd like

• Function to download/export an image of individual visualization
• The Visualizations should be optimized for static use (labelling not interactive for these cases)

Scope

• We will only offer one file type for export: PNG
• We will adjust the image download to only show the necessary information (e.g. certain interactive UI elements, such as menus etc.)
• Metadata: Timestamp on the download

Requirements BAKOM

• On the publish page, a download-button should be available
• The visualization is downloadable as .png file with an appropriate resolution
• The filename should have a logical definition (f.e. publisher-downloadDate or visualizationTitle-downloadDate)

The visualization itself should ideally contain the following information

• The dataset name
• date of the dataset
• selected filters
• source of the data
• visualize reference

The file should have the following information in the metadata

• download time
• publisher of the visualization
• link to the visualization
• dataset name and version

Things to think about (now or later)

• How do we deal with graph types without scales, f.e. Pie-charts. There, it is very difficult to assume the values of a specific field. -> This shows again the importance of annotations.
• In the regular publishable visualization the labels are rather small, maybe they should be in the case of an export a bit larger.

A separate issue has been created to download dashboards as images / PDFs here: #1929
