Donuts chart on nodes

[EdouardPan]

Description of new feature

This demand concerns the property 'Pie chart background'.

Currently you can draw a pie chart for each node. I do not see the possibility to create donut chart (if I am wrong, tell me, I will be delighted!). Would it be possible to consider it?

Or would it be possible to have the possibility to set pie drawing behind the basic node. So that, for instance, you can set the style node to:

{
   'label': 'xxxx',
   'background-opacity': 100,
   'background-color': 'white',
   'pie-size': '110%',
   'pie-order': 'background',    ##NEW PROPERTY## 
   'pie-1-background-opacity': ...,
   'pie-1-background-color': ...,
   'pie-1-background-size': ...
}

Thus the 'normal' node will be over the pie.

Or you could propose a property border for each slice of the pie:

{
   'pie-1-border-color': ...,
   'pie-1-border-width': ...
}

Thank you in advance.

Pie properties will be removed in v4. See #2019

There are many charting libraries that generate PNGs or SVGs for pie charts, doughnut charts, etc. You can use them as background images.
