...I hope you will like it, It is almost 90% as that of original pic, some features that are cosmetic might be missing. The biggest issue in its making was that there is no equation given to describe the basic curve (curve in gray color in your pic) so it consumed more time to plot it then to do rest of stuff. Any ways it was a good exercise.
Waiting for your feedback,
Regards,
