@@ -493,7 +493,7 @@ All marks support the following style options:
 * **clip** - whether and how to clip the mark
 * **tip** - whether to generate an implicit [pointer](../interactions/pointer.md) [tip](../marks/tip.md) <VersionBadge version="0.6.7" />
 
-If the **clip** option is *frame* (or equivalently true), the mark is clipped to the frame’s dimensions; if the **clip** option is null (or equivalently false), the mark is not clipped. If the **clip** option is *sphere* or a GeoJSON object with a polygonal geometry <VersionBadge pr="2243" />, then the mark will be clipped to the projected geometry (_e.g._, the front hemisphere when using the orthographic projection). A [geographic projection](./projections.md) is required for the sphere.
+If the **clip** option is *frame* (or equivalently true), the mark is clipped to the frame’s dimensions. If the **clip** option is null (or equivalently false), the mark is not clipped. If the **clip** option is *sphere*, the mark will be clipped to the projected sphere (_e.g._, the front hemisphere when using the orthographic projection); a [geographic projection](./projections.md) is required in this case. Lastly if the **clip** option is a GeoJSON object <VersionBadge pr="2243" />, the mark will be clipped to the projected geometry. 
 
 If the **tip** option is true, a [tip mark](../marks/tip.md) with the [pointer transform](../interactions/pointer.md) will be derived from this mark and placed atop all other marks, offering details on demand. If the **tip** option is set to an options object, these options will be passed to the derived tip mark. If the **tip** option (or, if an object, its **pointer** option) is set to *x*, *y*, or *xy*, [pointerX](../interactions/pointer.md#pointerX), [pointerY](../interactions/pointer.md#pointerY), or [pointer](../interactions/pointer.md#pointer) will be used, respectively; otherwise the pointing mode will be chosen automatically. (If the **tip** mark option is truthy, the **title** channel is no longer applied using an SVG title element as this would conflict with the tip mark.)
