How to set different radius for different parts of the pie chart in d3.js?

Good morning comrades!
Create a chart for one site.
Create a pie chart of labor is not caused.
But as previously created charts was not faced with the problem to specify different radii for different parts of the "pie".
Here's what I did.
And you want to reduce the radius for the green part of the chart.
Seen somewhere in the Internet that it is possible for each piece of the graph to set your parameters, but where to dig and did not understand. Anyone had experience creating schedules 3d.js tell me how to write individual parameters for each individual piece of the chart.
Thank you for your attention.
