Export the tables, ranges and embedded documents

### Task Summary

Nine visualizations implement `StandaloneCodeGenerator`, and what they have in common is that the output is not a plot drawn from numbers: a table rendered as a figure, a range a reader moves, an image or an HTML document passed through, and the waterfall, which reads as a chart but is built by accumulating rows rather than plotting them.

The waterfall plots every row and appends the total as a bar of its own, rather than consuming the last row to make one.

Step 15 of 27 in #8325. It needs #8327 for the trait. The waterfall's behaviour is filed separately as #7974 and closes with this work.
