wolffd@0 25 All Graphviz attributes are specified by name-value pairs. Thus, to
wolffd@0 26 set the fillcolor of a node <html:code>abc</html:code>, one would use
wolffd@0 27 </html:p>
wolffd@0 28 <html:p>
wolffd@0 29 <html:code>abc [fillcolor = red]</html:code>
wolffd@0 30 </html:p>
wolffd@0 31 <html:p>
wolffd@0 32 Similarly, to set the arrowhead style of an edge <html:code>abc -> def</html:code>,
wolffd@0 33 one would use
wolffd@0 34 </html:p>
wolffd@0 35 <html:p>
wolffd@0 36 <html:code>abc -> def [arrowhead = diamond]</html:code>
wolffd@0 37 </html:p>
wolffd@0 38 <html:p>
wolffd@0 39 Further details concerning the setting of attributes can be found
wolffd@0 40 in the description of the

wolffd@0 59 Some attributes, such as
wolffd@0 60 <html:a rel="attr">dir</html:a> or <html:a rel="attr">arrowtail</html:a>, are
wolffd@0 61 ambiguous when used in
wolffd@0 62 <html:a href="http://www.graphviz.org/doc/info/lang.html">DOT</html:a>
wolffd@0 63 with an undirected graph since the head and tail of an edge are meaningless.
wolffd@0 64 As a convention, the first time an undirected edge appears, the
wolffd@0 65 <html:a href="http://www.graphviz.org/doc/info/lang.html">DOT</html:a>
wolffd@0 66 parser will assign the left node as the tail node and the right node as
wolffd@0 67 the head. For example, the edge <html:code>A -- B</html:code> will have tail <html:code>A</html:code>
wolffd@0 68 and head <html:code>B</html:code>. It is the user's responsibility to handle such
wolffd@0 69 edges consistently. If the edge appears later, in the format
wolffd@0 70 </html:p>
wolffd@0 71 <html:p>
wolffd@0 72 <html:code>B -- A [taillabel = "tail"]</html:code>
wolffd@0 73 </html:p>
wolffd@0 74 <html:p>
wolffd@0 75 the drawing will attach the tail label to node <html:code>A</html:code>.
wolffd@0 76 To avoid possible confusion when such attributes are required, the user
wolffd@0 77 is encouraged to use a directed graph.
wolffd@0 78 If it is important to make the graph appear undirected, this can be
wolffd@0 79 done using the <html:a rel="attr">dir</html:a>, <html:a rel="attr">arrowtail</html:a>
wolffd@0 80 or <html:a rel="attr">arrowhead</html:a> attributes.

wolffd@0 168 These specify the order in which nodes and edges are drawn in concrete
wolffd@0 169 output. The default <html:span class="val">breadthfirst</html:span> is the simplest, but when the graph
wolffd@0 170 layout does not avoid edge-node overlap, this mode will sometimes have
wolffd@0 171 edges drawn over nodes and sometimes on top of nodes. If the mode
wolffd@0 172 <html:span class="val">nodesfirst</html:span> is chosen, all nodes are drawn first, followed by the
wolffd@0 173 edges. This guarantees an edge-node overlap will not be mistaken for
wolffd@0 174 an edge ending at a node. On the other hand, usually for aesthetic
wolffd@0 175 reasons, it may be desirable that all edges appear beneath nodes, even
wolffd@0 176 if the resulting drawing is ambiguous. This can be achieved by choosing
wolffd@0 177 <html:span class="val">edgesfirst</html:span>.

wolffd@0 191 <html:p>
wolffd@0 192 These specify the granularity of packing connected components when
wolffd@0 193 the <html:a rel="attr">pack</html:a> attribute is true. A value of <html:span class="val">node</html:span> causes
wolffd@0 194 packing at the node and edge label, with no overlapping of these objects.
wolffd@0 195 This produces a layout with the least area, but it also allows interleaving,
wolffd@0 196 where a node of one component may lie between two nodes in another
wolffd@0 197 component. A value of <html:span class="val">graph</html:span> does a packing using the bounding box of the
wolffd@0 198 component. Thus, there will be a rectangular region around a component
wolffd@0 199 free of elements of any other component.
wolffd@0 200 A value of <html:span class="val">clust</html:span> guarantees that top-level clusters are kept intact.
wolffd@0 201 What effect a value has also depends on the layout algorithm. For
wolffd@0 202 example, neato does not support clusters, so a value of <html:span class="val">clust</html:span> will
wolffd@0 203 have the same effect as the default <html:span class="val">node</html:span> value.

wolffd@0 368 At present, used in ps2, cmap, i*map and svg formats.
wolffd@0 369 For all these formats, URLs can be attached to nodes, edges and

wolffd@0 378 For other output, the active area is its bounding box.
wolffd@0 379 The active area for a cluster is its bounding box.
wolffd@0 380 For edges, the active areas are small circles where the edge contacts its head
wolffd@0 381 and tail nodes. In addition, for svg, cmapx and imap, the active area
wolffd@0 382 includes a thin polygon approximating the edge. The circles may
wolffd@0 383 overlap the related node, and the edge URL dominates.
wolffd@0 384 If the edge has a label, this will also be active.

wolffd@0 446 When attached to the root graph, this color is used as the background for
wolffd@0 447 entire canvas. When a cluster attribute, it is used as the initial
wolffd@0 448 background for the cluster. If a cluster has a filled
wolffd@0 449 <html:a rel="attr">style</html:a>, the
wolffd@0 450 cluster's <html:a rel="attr">fillcolor</html:a> will overlay the
wolffd@0 451 background color.
wolffd@0 452 </html:p>
wolffd@0 453 <html:p>
wolffd@0 454 If no background color is specified for the root graph, no graphics
wolffd@0 455 operation are performed on the background. This works fine for
wolffd@0 456 PostScript but for bitmap output, all bits are initialized to something.
wolffd@0 457 This means that when the bitmap output is included in some other
wolffd@0 458 document, all of the bits within the bitmap's bounding box will be
wolffd@0 459 set, overwriting whatever color or graphics where already on the page.
wolffd@0 460 If this effect is not desired, and you only want to set bits explicitly
wolffd@0 461 assigned in drawing the graph, set <html:a rel="attr">bgcolor</html:a>="transparent".

wolffd@0 841 In the former case, known PostScript font names such as
wolffd@0 842 <html:code>Times-Roman</html:code> will be used in the output.
wolffd@0 843 In the latter case, the fontconfig font conventions
wolffd@0 844 are used. Thus, <html:code>Times-Roman</html:code> would be treated as
wolffd@0 845 <html:code>Nimbus Roman No9 L</html:code>. These last two options are useful
wolffd@0 846 with SVG viewers that support these richer fontname spaces.

wolffd@0 1024 Attribute controlling how an image fills its
wolffd@0 1025 containing node. In general, the image is given its natural size,
wolffd@0 1026 (cf. <html:a rel="attr">dpi</html:a>),
wolffd@0 1027 and the node size is made large enough to contain its image, its
wolffd@0 1028 label, its margin, and its peripheries.
wolffd@0 1029 Its width and height will also be at least as large as its
wolffd@0 1030 minimum <html:a rel="attr">width</html:a> and <html:a rel="attr">height</html:a>.
wolffd@0 1031 If, however, <html:code>fixedsize=true</html:code>,
wolffd@0 1032 the width and height attributes specify the exact size of the node.

wolffd@0 1034 <html:p>
wolffd@0 1035 During rendering, in the default case (<html:code>imagescale=false</html:code>),
wolffd@0 1036 the image retains its natural size.
wolffd@0 1037 If <html:span class="val">true</html:span>,
wolffd@0 1038 the image is uniformly scaled (i.e., its aspect ratio is
wolffd@0 1039 preserved) to fit inside the node.
wolffd@0 1040 At least one dimension of the image will be as large as possible
wolffd@0 1041 given the size of the node.
wolffd@0 1042 When <html:span class="val">width</html:span>,
wolffd@0 1043 the width of the image is scaled to fill the node width.
wolffd@0 1044 The corresponding property holds when <html:tt>imagescale=height</html:tt>.
wolffd@0 1045 When <html:span class="val">both</html:span>,
wolffd@0 1046 both the height and the width are scaled separately to fill the node.

wolffd@0 1049 In all cases, if a dimension of the image is larger than the

wolffd@0 1052 expansion, if <html:code>imagescale=true</html:code>, width and height are
wolffd@0 1053 scaled uniformly.

wolffd@0 1411 Technique for optimizing the layout. If <html:a rel="attr">mode</html:a> is <html:span class="val">major</html:span>,
wolffd@0 1412 neato uses stress majorization. If <html:a rel="attr">mode</html:a> is <html:span class="val">KK</html:span>,
wolffd@0 1413 neato uses a version of the gradient descent method. The only advantage
wolffd@0 1414 to the latter technique is that it is sometimes appreciably faster for

wolffd@0 1419 There are two new, experimental modes in neato, <html:span class="val">hier</html:span>, which adds a top-down

wolffd@0 1431 <html:p>
wolffd@0 1432 This value specifies how the distance matrix is computed for the input
wolffd@0 1433 graph. The distance matrix specifies the ideal distance between every
wolffd@0 1434 pair of nodes. neato attemps to find a layout which best achieves
wolffd@0 1435 these distances. By default, it uses the length of the shortest path,
wolffd@0 1436 where the length of each edge is given by its <html:a rel="attr">len</html:a>
wolffd@0 1437 attribute. If <html:a rel="attr">model</html:a> is <html:span class="val">circuit</html:span>, neato uses the
wolffd@0 1438 circuit resistance
wolffd@0 1439 model to compute the distances. This tends to emphasize clusters. If
wolffd@0 1440 <html:a rel="attr">model</html:a> is <html:span class="val">subset</html:span>, neato uses the subset model. This sets the
wolffd@0 1441 edge length to be the number of nodes that are neighbors of exactly one
wolffd@0 1442 of the end points, and then calculates the shortest paths. This helps

wolffd@0 1576 Determines if and how node overlaps should be removed. Nodes are first
wolffd@0 1577 enlarged using the <html:a rel="attr">sep</html:a> attribute.
wolffd@0 1578 If <html:span class="val">true</html:span>, overlaps are retained.
wolffd@0 1579 If the value is <html:span class="val">scale</html:span>, overlaps are removed by uniformly scaling in x and y.
wolffd@0 1580 If the value converts to <html:span class="val">false</html:span>, node overlaps are removed by a
wolffd@0 1581 Voronoi-based technique.
wolffd@0 1582 If the value is <html:span class="val">scalexy</html:span>, x and y are separately
wolffd@0 1583 scaled to remove overlaps.
wolffd@0 1584 If the value is <html:span class="val">orthoxy</html:span> or <html:span class="val">orthoyx</html:span>, overlaps
wolffd@0 1585 are moved by optimizing two constraint problems, one for the x axis and
wolffd@0 1586 one for the y. The suffix indicates which axis is processed first.
wolffd@0 1587 If the value is <html:span class="val">ortho</html:span>, the technique is similar to <html:span class="val">orthoxy</html:span> except a
wolffd@0 1588 heuristic is used to reduce the bias between the two passes.
wolffd@0 1589 If the value is <html:span class="val">ortho_yx</html:span>, the technique is the same as <html:span class="val">ortho</html:span>, except
wolffd@0 1590 the roles of x and y are reversed.
wolffd@0 1591 The values <html:span class="val">portho</html:span>, <html:span class="val">porthoxy</html:span>, <html:span class="val">porthoxy</html:span>, and <html:span class="val">portho_yx</html:span> are similar
wolffd@0 1592 to the previous four, except only pseudo-orthogonal ordering is
wolffd@0 1593 enforced.
wolffd@0 1594 </html:p>
wolffd@0 1595 <html:p>
wolffd@0 1596 If the value is <html:span class="val">compress</html:span>, the layout will be scaled down as much as
wolffd@0 1597 possible without introducing any overlaps, obviously assuming there are
wolffd@0 1598 none to begin with.
wolffd@0 1599 </html:p>
wolffd@0 1600 <html:p>
wolffd@0 1601 If the value is <html:span class="val">ipsep</html:span>, and the layout is done by neato with
wolffd@0 1602 <html:a rel="attr">mode</html:a>="ipsep", the overlap removal constraints are
wolffd@0 1603 incorporated into the layout algorithm itself.
wolffd@0 1604 N.B. At present, this only supports one level of clustering.
wolffd@0 1605 </html:p>
wolffd@0 1606 <html:p>
wolffd@0 1607 If the value is <html:span class="val">vpsc</html:span>, overlap removal is similarly to <html:span class="val">ortho</html:span>, except
wolffd@0 1608 quadratic optimization is used to minimize node displacement.
wolffd@0 1609 N.B. At present, this mode only works when <html:a rel="attr">mode</html:a>="ipsep".
wolffd@0 1610 </html:p>
wolffd@0 1611 <html:p>
wolffd@0 1612 Except for fdp, the layouts assume <html:code>overlap="true"</html:code> as the default.
wolffd@0 1613 Fdp first uses a number of passes using built-in, force-directed technique
wolffd@0 1614 to remove overlaps. Thus, fdp accepts <html:a rel="attr">overlap</html:a> with an integer
wolffd@0 1615 prefix followed by a colon, specifying the number of tries. If there is
wolffd@0 1616 no prefix, no initial tries will be performed. If there is nothing following
wolffd@0 1617 a colon, none of the above methods will be attempted. By default, fdp
wolffd@0 1618 uses <html:code>overlap="9:portho"</html:code>. Note that <html:code>overlap="true"</html:code>,
wolffd@0 1619 <html:code>overlap="0:true"</html:code> and <html:code>overlap="0:"</html:code> all turn off all overlap
wolffd@0 1620 removal.
wolffd@0 1621 </html:p>
wolffd@0 1622 <html:p>
wolffd@0 1623 Except for the Voronoi method, all of these transforms preserve the
wolffd@0 1624 orthogonal ordering of the original layout. That is, if the x coordinates
wolffd@0 1625 of two nodes are originally the same, they will remain the same, and if
wolffd@0 1626 the x coordinate of one node is originally less than the x coordinate of
wolffd@0 1627 another, this relation will still hold in the transformed layout. The
wolffd@0 1628 similar properties hold for the y coordinates.
wolffd@0 1629 This is not quite true for the "porth*" cases. For these, orthogonal
wolffd@0 1630 ordering is only preserved among nodes related by an edge.
