calculate area of circle
Please add ability to calculate area of circle (in addition to the existing height/width). This will make it easier for users to create ACCURATE data visualizations/infographics!
This calculation should be included in Photoshop, InDesign, After Effects -- basically, any tool someone may want to use to create a data viz.

Area of a circle is pi multiplied by a diameter of a circle, no big deal to calculate it. If you want to automate the process — you can use custom plugins like Dynamic Measure by AstuteGraphics.
The other thing is if you want to control the size of the circle by entering the desired area. Like 'create a circle with area x' or 'transform a circle to have the area y'. Is that you want? Plugins can’t do that so far.
Still, there are methods to automate it, like actions to create circle presets, libraries, so on. It’d be easier to understand the request if you provide some examples you want to create.
Anyway, bezier ellipses are not real circles, but a good approximation. So no ACCURACY is possible anyway :)
