Include nodes with no connections in Chord chart? about bkcharts HOT 5 CLOSED

I would love to have the labels look more like this, where there are ticks for residue number then just have text for the categories.

from bkcharts.

You can include nodes without connections, in fact there are some in the generated graph above. Is just that their representation (size) is equally proportional to the number of edges they have.

Just to check I understand what you're asking for:

1. New way of displaying names, where you can mix a linear scale with a name (like the example above)
2. Give every node the same width. (Maybe make this configurable ?)

This are features not included now, you might need to modify the code to generate the chart or if you're not in a hurry, we can plan them and add them to the already existing implementation (I'm quite busy till mid-June).

FYI as an aside, the new pandas version has broken bokeh.charts with its changed groupby behavior (returning Interval objects)

from bkcharts.

So an updated is needed. I'm more than happy of updating and maintaining this chart interface. Maybe we can discuss it here and expect an update in mid-June ? That works for you ?

Yes, e.g., have a name for the group, then a number for each item in the group which goes along the circular number line/semicircle.

Give every node the same width. (Maybe make this configurable ?)

Yes. Perhaps this would be similar to you dot chord chart from #13 (originally here: bokeh/bokeh#4227).

Depending on the timing and demands of the project I'm working on, I may end up looking at how other packages (nxviz, plotly, or some R packages, circlize: chordDiagram() or chorddiag) implement their chord charts. This could provide more concrete ideas.
