Keeps a chart's words in the language MAIDR speaks: when the reader changes it, the chart is converted again and MAIDR handed the result.
Charts no longer in the page are let go as others are added, so a page that draws its diagrams again and again holds on to none of the old ones.
Where the chart is bound
The language its words are written in now
The chart data written in it
Converts the chart again in another language
