A conceptual question:
I would like to create a calendar visualization and use Plot.cell() to have one cell per day. If I now want to have a data-driven way to plot each day not just by color but let’s say by dividing each cell into 16 subcells and use the fill of these subcell to indicate a value. How would I go about it?
Create the “top-level” calendar with Plot to have a cell per day. Then use d3 to work on the resulting SVG and refine with the subcells.
Is there a way to recursively define a Plot.cell()'s as part of Plot.cell() or is Plot.cell as a mark the lowest level element of Plot to build upon?
