+/// \class sf::CircleShape
+/// \ingroup graphics
+///
+/// This class inherits all the functions of sf::Transformable
+/// (position, rotation, scale, bounds, ...) as well as the
+/// functions of sf::Shape (outline, color, texture, ...).
+///
+/// Usage example:
+/// \code
+/// sf::CircleShape circle;
+/// circle.setRadius(150);
+/// circle.setOutlineColor(sf::Color::Red);
+/// circle.setOutlineThickness(5);
+/// circle.setPosition(10, 20);
+/// ...
+/// window.draw(circle);
+/// \endcode
+///
+/// Since the graphics card can't draw perfect circles, we have to
+/// fake them with multiple triangles connected to each other. The
+/// "points count" property of sf::CircleShape defines how many of these
+/// triangles to use, and therefore defines the quality of the circle.
+///
+/// The number of points can also be used for another purpose; with
+/// small numbers you can create any regular polygon shape:
+/// equilateral triangle, square, pentagon, hexagon, ...
+///
+/// \see sf::Shape, sf::RectangleShape, sf::ConvexShape
+///
