POJUNG layout question

Body
copied!<p>I have some graph, which I want to display using <a href="http://jung.sourceforge.net/" rel="nofollow noreferrer">JUNG2</a> like in the image below.</p> <p><img src="https://i.stack.imgur.com/RkEeZ.jpg" alt="enter image description here"></p> <p>I've played with some layouts of JUNG2, but I'm always getting an image like this:</p> <p><img src="https://i.stack.imgur.com/Gq40X.png" alt="enter image description here"></p> <p>Is it possible to lay out the graph as I wish without writing a new layout?</p> <p>Thanks in advance</p> <p>Dmitri</p> <p>UPD: Here is the code I used for visualizing the graph:</p> <pre><code>private Embedded createSampleGraph() { Embedded imageComponent = null; try { final DocumentBuilderFactory docBuilderFactory = DocumentBuilderFactory .newInstance(); final DocumentBuilder docBuilder = docBuilderFactory.newDocumentBuilder(); final Document document = docBuilder.newDocument(); final Element svgelem = document.createElement("svg"); document.appendChild(svgelem); final SVGGraphics2D graphic2d = new SVGGraphics2D(document); final Graph<String, String> graph = createGraph(); final VisualizationImageServer<String, String> server = createServer(graph); server.printAll(graphic2d); final Element el = graphic2d.getRoot(); el.setAttributeNS(null, "viewBox", "0 0 350 350"); el.setAttributeNS(null, "style", "width:100%;height:100%;"); final ByteArrayOutputStream bout = new ByteArrayOutputStream(); final Writer out = new OutputStreamWriter(bout, "UTF-8"); graphic2d.stream(el, out); final JungResource source = new JungResource(bout); TPTApplication.getCurrentApplication().addResource(source); imageComponent = new Embedded("", source); imageComponent.setWidth(DEFAULT_WIDTH_PIXELS, UNITS_PIXELS); imageComponent.setHeight(DEFAULT_HEIGHT_PIXELS, UNITS_PIXELS); imageComponent.setMimeType("image/svg+xml"); addComponent(imageComponent); } catch (final UnsupportedEncodingException exception) { LOGGER.error(ErrorCodes.M_001_UNSUPPORTED_ENCONDING, exception); } catch (final SVGGraphics2DIOException exception) { LOGGER.error(ErrorCodes.M_002_SVG_GRAPHICS_2D_IO, exception); } catch (final ParserConfigurationException exception) { LOGGER.error(ErrorCodes.M_003_PARSER_CONFIGURATION, exception); } return imageComponent; } private VisualizationImageServer<String, String> createServer( final Graph<String, String> aGraph) { final Layout<String, String> layout = new FRLayout<String, String>( aGraph); layout.setSize(new Dimension(300, 300)); final VisualizationImageServer<String, String> vv = new VisualizationImageServer<String, String>( layout, new Dimension(350, 350)); vv.getRenderContext().setVertexLabelTransformer( new ToStringLabeller<String>()); return vv; } private Graph<String, String> createGraph() { final Graph<String, String> graph = new DirectedSparseMultigraph<String, String>(); final String vertex1 = "IE"; final String vertex2 = "P1"; final String vertex3 = "P2"; final String vertex4 = "P3"; final String vertex5 = "FE"; graph.addVertex(vertex1); graph.addVertex(vertex2); graph.addVertex(vertex3); graph.addVertex(vertex4); graph.addVertex(vertex5); graph.addEdge("1", vertex1, vertex2, EdgeType.DIRECTED); graph.addEdge("2", vertex2, vertex3, EdgeType.DIRECTED); graph.addEdge("3", vertex3, vertex5, EdgeType.DIRECTED); graph.addEdge("4", vertex1, vertex4, EdgeType.DIRECTED); graph.addEdge("5", vertex4, vertex5, EdgeType.DIRECTED); return graph; } </code></pre> <p>UPD 17.03.2011</p> <p>Now I can draw a graph like this:</p> <p><img src="https://i.stack.imgur.com/nQb3U.png" alt="enter image description here"></p>
