This plugin generates a vowel diagram used for showing a language inventory of vowels.
The simplest usage of the plugin is to create a code block with the vowel-chart tag, and write vowels in the IPA:
```vowel-chart
; example: Italian vowels
i e ɛ a ɔ o u
```

Another way to add vowels is with the add command, with it you can specify a position and a label, there are three ways of specifying position, as follows, they can be mixed freely.
Numerical coordinates start with (0, 0) at the top-left and end in (2, 3) in the bottom-right.
add (0, 0) "i"
add (2, 3) "ɑ"
add (0, 3) "æ"
add (2, 0) "u"

Use the keywords high/low/mid/close/open/front/central/back to position the vowels, the order is irelevant. Also supports the keyword near for intermediary positions.
add high front "i"
add high near-front "y"
add mid front "e"
add mid near-front "ø"
add mid back "o"
add low central "a"
add high back "ɯ"

This positions vowels by their position in the IPA chart. In that option the label is optional, if absent the same text in the position is used.
The position is defined just by the first character in brackets, that way diacritics are automatically supported.
add [ɜ] "ʌ"
add [a] "a ã"
add [i]
add [u]
add [e]
add [o]
add [ɛ̃]
add [ɔ̃]

The commands add right and add left create a dot at the specified position and place the text to the right or left of it:
add [a] "a aː"
add left near-front high-mid "eː"
add right (0, 0) "i"
ɛ ɔ oː u

add commands can be used together with the simple usage.
In the charts above, the position of the low vowels [æ a] is different from the original IPA chart, this behaviour can be changed by the config centralLowVowel false command:

This option can also be turned off by default on the plugin settings.
There are 4 chart layout options, they can be chosen with the layout command.
layout trapezoid like the original IPA chart

layout triangle an alternative to the original

layout square

layout formant arranged according to formants

The default layout can be set in the plugin settings.
The command config size <size> defines the size of the chart. The default can be set in the plugin settings.
The size is the vertical distance in pixels from the high line to the high-mid line.
config size 25
i e ɛ a ɔ o u

config size 52
i e ɛ a ɔ o u
