ODF has no name for this chart type, so the file says two things at once, the
way a histogram already does: chart:class names the scatter chart, which is the
nearest a reader that knows nothing of correlation circles can make of it, and
coext:class beside it names the type itself. A reader that knows the coext name
gets the chart back as it was saved.
The series need no new shape in the file. The feature column is the range of
the series and the two dimension columns are a domain each, which is where a
bubble chart already keeps its x and y values, so both the reading and the
writing of them follows the bubble path rather than a new logic.
The schema the tests validate against lists the values coext:class may take, so
the new one is added there beside the histogram.
The test document is one block of five columns: three features and then the two
dimensions, the shape the wizard asks for. The test checks after a round trip
that the chart type came back, that the file carries both class names, and that
every series still holds its feature column beside the two dimension columns.
