[Feature] Improve rendering one-week subset of days in calendar

[juand-v]

What problem does this feature solve?

Allowing a one-week calendar to render only a subset of days improves UX when rendering the graph in devices with small screens. The proposal is to support these scenarios without showing blank day columns:

Initial segment of a week

Middle segment of a week

Single-day view

In mobile interfaces, this feature could allow users to choose between displaying five days, three days, or just one day (rendering multiple charts per day as needed).

What does the proposed API look like?

The API will stay as it is, the fix will focus on styling and not rendering extra nodes.

One could use pie with coordinateSystem: 'cartesian2d' - Demo.
This option is missing in the API documentation.
