The Point mark enables end users to create a point with width, color, and opacity attributes.

The Point annotation mark is always displayed as a circle with a diameter (in image coordinates) equal to the mark's Width. It is also rasterized as a circle with the same diameter; however it might look squeezed on display after rasterization if the image's horizontal and vertical resolution values are different.
