Description

Converts tables found in the rendered body of the macro into a Graphviz graph. Each row found in a table is converted to a node relationship. The Flowchart macro is used for the rendering, so it must be enabled and working correctly. This macro simplifies use of the Graphviz support by eliminating or significantly reducing the need to know the dot language. Advanced users will still need to consult the Graphviz documentation for the multitude of attributes and settings that are possible.

The columns in the table are interpreted as follows:

Node with label equal to the column. The source of a relationship. This is the only required column.
Node with label equal to the column. The target of a relationship.
Relationship attributes.
Source node attributes.
Target node attributes.
First cluster number. A cluster is a subgraph that contains the source and target nodes for this row.
First cluster attributes.
Second cluster number. The second cluster is a subgraph that contains the first cluster.
Second cluster attributes.

Attributes are defined by Graphviz for nodes, relationships, and subgraphs (clusters). They are specified as comma separated list. Attribute values containing blanks must be surrounded by double quotes. Some commonly used attributes are:

label - text to display
style - examples: filled, bold, dotted, dashed, invis (for invisible)
fillcolor - node fill color
fontname - standard font name (enclosed in double quotes if contains a blank)
fontsize - standard font size
fontcolor - color usually specified as a color name like blue, grey, lightyellow
shape - examples: rect, box, circle, ellise, triangle, polygon (together with sides attibutes), diamond, ...
sides - number of sides for a polygon shape
peripheries - number of node boundaries

Parameters

Macro specific parameters

Macro Editor Label	Default	Description	Macro Parameter

Macro Editor Label	Default	Description	Macro Parameter
Direction of graph (rankdir)	LR	Sets the graphviz rankdir parameter TB – top to bottom LR – left to right	direction
Node parameters		Sets the graphviz node parameter. The default node attributes are taken from the default Flowchart macro behavior. By specifying the node parameter, you can override these defaults or add additional default attributes. See the Graphviz Documentation for information on attributes and settings.	node
Edge parameters		Sets the graphviz edge parameter. The default edge attributes are taken from the default Flowchart macro behavior. By specifying the edge parameter, you can override these defaults or add additional default attributes. See the Graphviz Documentation for information on attributes and settings.	edge
Replace variables		A comma separated list of key:value pairs that is used to convert column values to attributes. If a column value for an attribute column matches one of the keys, the associated value replaces the column value. This makes it easy to associate attributes to column data. If more than one attribute needs to be specified for a key, enclose the value in a single quote so that the comma gets treated as a attribute separator.	replace
Table ids or numbers to include	all	Comma separated list of table ids and/or table numbers contained within the body of the macro that is used as the data for the graph.	tables
Column numbers to include		Allows selection of the columns of the table that is used for the graph. It must be a comma separated list of 1 or more positive integers in any order. The default value of blank represents columns=1,2,3,4,5,6,7,8,9. If the table does not contain the column indicated, it is ignored. For example, if columns=3,13 then column 3 is used for the source node and column 13 is used for the target node of the relationship. All other columns are ignored.	columns

Other Parameters

All other parameters are passed through to Graphviz for setting any global Graphviz parameter. Some common examples are:

ranksep - Separation in inches between nodes.
bgcolor - Background color.
size - Size specified as width, height in inches. Example: size="3,5".

Usage

Simple

{graph-from-table}
| A | B |
| A | C |
{graph-from-table}

Relationship and node attributes

Note that headings are ignored

{graph-from-table}
|| heading 1 ignored || heading 2 ignored ||
| A node | B node | label="relationship 1", style=dashed | style=normal | fillcolor=lightblue |
| A node | C node |
| A node | D node | style=invis |
{graph-from-table}

Multiple tables and using parameters

{graph-from-table:node=fillcolor=lightblue,fontsize=20|edge=style=bold,color=red| replace=key1:'style=dashed, color=blue', key2:style=invis|ranksep=2.0}
| A node | B node | | shape=polygon,sides=8,peripheries=3 | |
| A node | B node | | style=dashed |
| A node | C node |
| A node | D node | key2 |

Here is a second table
| E | F | key1 |
| F | G | key1 |
{graph-from-table}

Subgraphs - clusters

{graph-from-table:direction=LR|ranksep=1.5|node=fillcolor=lightblue,fontsize=20| edge=style=bold,color=red|replace=key1:style=dashed}
| A node | B node | label="r1" | | | 100 | key1 |
| F | G | key1 | | | 100 | label="cluster 100" |
| X | Y | key1 | | | 200 | label="cluster 200" | 2000 | label="cluster 2000" |
{graph-from-table}
