Intriguing option. So you assign virtual locations based on the layouting algorithm, and then use neo4j-spatial's 'export to PNG' capabilities, which also makes use of SLD for styling (geoserver-like styling, using geotools inside, of course). This is certainly not an option I had every considered, but I can no reason it would not work.
Could you tell us more about the domain? We could certainly give suggestions on approaches on how to pick a coordinate system, and how to style the results in the rendered image. I am currently using the amanzi-sld Ruby gem for styling layers (just a wrapper DLS on top of SLD XML making it easier). I have only tested this with real geographic data (streets, rivers, lakes, parks, etc.) It would be cool to see it in use on something outside that domain.
