Partition padding, so as to preserve relative areas?

[mbostock]

If you do the simple thing and subtract a fixed amount of padding from the computed cells in a partition layout, you introduce distortion because small cells are disproportionately affected. It might be nice if the partition layout knew about padding, so that it could preserve the relative areas of padded cells.

See #19 for a description of a similar problem with the treemap layout.

This is an interesting idea but I’m not going to pursue it immediately. Unlike #19, however, this presumably would be much easier to implement…
