This visualization presents a full year of events on a circular "year wheel," with each month and quarter arranged radially. It uses SVG rendering in React with D3 v4, employing date-based computations like `Date.prototype.getDOY` to convert calendar dates into angular positions. Event bars and shaded time spans are placed along the wheel’s rings using custom path drawing with trigonometric functions, while hover effects and colored categories make event types distinguishable.
