Graphical representations of provenance information

Inspired by Southampton tool suite for provenance. Only takes activities, entities, agents and their main relations into account.

The diagrams below use a simple json-representation of some example data, which was generated automatically from database data using a django web application. The json-file is available at this link:

• example.json

The javascript files are linked here:

• provgraphs-example.js: javascript customiyed for provenance, with color and shape definitions
• sankey.js: contains general sankey function from d3.js examples

Sankey chart

Based on https://bost.ocks.org/mike/sankey/.

Force directed graph layout

See e.g. http://bl.ocks.org/mbostock/4062045 for an example. The shape and color of nodes is adjusted to the W3C representation of activities and entities.
