This example visualizes a dataset of authors with their birth and death dates by mapping each person to a position along a continuous, interactive Bézier-like curve. The rendering shows orange circles placed along a red skeleton curve, demonstrating a custom curve-subdivision algorithm. The code implements the visualization using D3 v3 for SVG rendering and data loading from a TSV file, while a custom `SDCurve` class defines the curve geometry with adjustable resolution and degree. Users can interact with the curve through mouse events, including dragging and double-clicking.
