Specifies the location of the `textinfo`.

Controls the orientation of the text inside chart sectors. When set to *auto*, text may be oriented in any direction in order to be as big as possible in the middle of a sector. The *horizontal* option orients text to be parallel with the bottom of the chart, and may make text smaller in order to achieve that goal. The *radial* option orients text along the radius of the sector. The *tangential* option orients text perpendicular to the radius of the sector.

Sets the font used for `textinfo` lying inside the sector.

Sets the font used for `textinfo` lying outside the sector.

Determines whether outside text labels can push the margins.

Sets the title of the chart. If it is empty, no title is displayed. Note that before the existence of `title.text`, the title's contents used to be defined as the `title` attribute itself. This behavior has been deprecated.

Sets the font used for `title`. Note that the title's font used to be set by the now deprecated `titlefont` attribute.

Specifies the location of the `title`. Note that the title's position used to be set by the now deprecated `titleposition` attribute.

Sets the horizontal domain of this pie trace (in plot fraction).

Sets the vertical domain of this pie trace (in plot fraction).

If there is a layout grid, use the domain for this row in the grid for this pie trace .

If there is a layout grid, use the domain for this column in the grid for this pie trace .

Sets the fraction of the radius to cut out of the pie. Use this to make a donut chart.

Determines whether or not the sectors are reordered from largest to smallest.

Specifies the direction at which succeeding sectors follow one another.

Instead of the first slice starting at 12 o'clock, rotate to some other angle.

Sets the fraction of larger radius to pull the sectors out from the center. This can be a constant to pull all slices apart from each other equally or an array to highlight one or more slices.

Deprecated in favor of `title.text`. Note that value of `title` is no longer a simple *string* but a set of sub-attributes.
