  • Problem: There are a number of svg maps presenting statistical information or locations for countries or regions. Every time a new information is presented the map is duplicated and adapted to the information to be shown. This leads to several problems: (1) increases the size of data to be stored - the same geographical information is copied every time (2) requires skills to manipulate these images using software or knowledge of the svg format and (3) requires several images to be corrected if the basic geographical information is changed. As an example the following maps are based on the same geographical information but present different data. Each time the map of 12 MB is copied and modified:

CSS files associated to svg images can be used to present information without changing the svg file. Entities from the picture can be coloured using their ids in a separate file. This file than can be used in association with the basic svg as a picture instead of creating new image every time. A simple text editor can be used to manipulate data given that the basic svg is formed in a convenient manner.

  • Who would benefit: Wikimedia Commons, editors
  • Proposed solution: Allow CSS files associated to svg files to be used as media.

Probably doable with the Graph extension? Ping @Yurik: --Tgr (WMF) (talk) 00:41, 20 November 2017 (UTC)
