Template:tree chart/documentation

Usage
This template produces one row in a "family tree"-like chart consisting of boxes and connecting lines based loosely on an -like syntax. It is meant to be used in conjunction with tree chart/start and tree chart/end. The chart is displayed as tables using  attributes, and may contain arbitrary  within the boxes.

Basic example
This code:

produces this:

This chart visually displays the information that I have a brother Joe and a little sister; my mom married my dad; and my dad's parents were Grandma and Grandpa; and my dad's parents had another child, Aunt Daisy. The code above produces a table of size 9 rows x 18 columns as shown below.

Parameters
The template accepts any number of unnamed parameters with each parameter specifying a tile or a box.
 * Boxes can contain arbitrary . The content of each box is specified using additional named parameters appended to the template call. Each box is three tiles wide and normally has a black border two pixels wide. Boxes can have any name that is a valid template parameter name, subject to a minimum of two alphabetical characters.
 * Tiles are line drawing symbols used to connect the boxes. They consist of various styles of horizontal and vertical lines along with corners and crossings as needed. Tiles are specified using their one- or two-character name: for the most common tiles, that character is more or less approximate to the tile's appearance. A special case of a tile is the empty tile, specified by a single space character. A table of available tiles is given below.

Style attributes
The appearance of the boxes in a row may be controlled by the following optional template parameters:
 * border specifies the width of the box border in pixels,
 * boxstyle can be used to append arbitrary declarations directly to the box style attributes. For example, the following code:

produces this chart:

Style attributes can even be set for individual boxes within each row, as in the example below:

which produces this:

Note: When specifying style attributes for individual named boxes, make sure the box names are aligned to the left side of the area reserved for them in the template call (as in " " instead of " " in the example above), otherwise the template will end up looking for a style parameter with spaces in its name.

The tree chart/start template also accepts an optional style parameter that can be used to set CSS styles for the entire diagram, and an optional align parameter to set the chart alignment.
