KRENN - diagrams

1. WHAT IS KRENN?

   krenn diagrams are a way to visualize (and navigate) data. It works best for a certain classes of data:
   appropriate data:

   • a (very) limited number of symmetric connected vertices of a graph (also with weighed distances).
   • items tagged with (partly) overlaying tags

2. Usage/Example: example for plain svg: open krenn_self_contained.svg in your browser

   svg embedded in a html-file: open example.html in your browser

3. Configuration:

   1. diagram types: there are currently 3 types of diagrams:

      1. flower:
         around a centerfield there are the connected fields.
         

      2. flagpole:
         from the vertical centerfield on the left the connected fields overlay and continue to the right (overlays are proportional to the weight of the connection)
         

      3. shelve:
         between 2 vertical centerfields there are the horizontal connected field (overlays are proportional to the weight of the connection)
         

   2. navigation (link-) configurations: there are 2 types of mapping between the elements of the diagram

      1. hash-based mapping a supplied hash with the ID as key and the link-target as value will connect clicks and URLs

      2. function-based mapping if you supply a function that uses the ID and produces a URL it will be hooked up to the click-event

   3. other configurations

      1. modify the configuration section of krenn.svg (dimensions, colors, transparency)
      2. modify the source-code which is quite straight-forward
