Design a clean, digital icon representing a medical doctor, featuring a simplified human figure dressed in a medical coat with a stethoscope around the neck for easy identification. Position the stethoscope symmetrically over both shoulders, and use soft, calming tones like light blue for the coat and white for the background, reinforcing the professional, approachable mood. The figure should have a clear outline and subtle details, such as a gentle smile, to convey friendliness. Ensure that the icon has uniform line thickness and crisp edges, optimized for clarity at both small and large digital resolutions. The icon should have no background, allowing it to blend seamlessly into various interfaces. Keywords: “medical doctor icon,” “stethoscope,” “professional,” “digital vector,” “approachable.”
