12	12	Provide automatic layout through KIML for the JGraph diagram library and develop a simple JGraph-based graph editor to test the integration with.

16		-The [[D3.js>>url:http://d3js.org/||shape="rect"]] library is a well-known and widely-used Javascript library for SVG-based visualizations and already comes with [[force-based graph layout >>url:http://bl.ocks.org/mbostock/4062045||shape="rect"]]algorithms. Implement an adapter that allows to use D3 with KlayJS.

	18	+* **Comment Attachment**
	19	+When computing a new layout for a diagram that contains comments (comparable to comments in source code), the comments often get placed far away of the nodes they refer to. This is because often the reference is not explicitly encoded in the original model. We have used a distance-based metric in the past to discover references automatically, but there are lots of ideas for improvement. This bachelor thesis would implement them, perhaps come up with additional ideas, and finally evaluate them in a thorough experiment.\\
20	20	* **Control Flow Graph Exploration / Visualization**
21	21	Use pragmatics concepts (automatic layout, focus & context) for exploring/visualizing control flow graphs and specific paths, eg. as computed by OTAWA WCET analysis tool, eg. using Klighd.
