Graphic skin recommendations?

[Timothy Buchanan]

Is there a skin available that has a simple graphic design with a wind rose?

Regarding Wind Rose (although I have not tried), it seems that there is even a WeeWX extension to generate a polar windrose graphic for standard WeeWX:

For graphical interface, may not mention one specific in respect to all developers, but to check WeeWX showcase:
