d3-geo-polygon
A D3 module for clipping and geometric operations on spherical polygons, enabling custom map projections.
What is d3-geo-polygon?
d3-geo-polygon is a JavaScript library for clipping and performing geometric operations on spherical polygons within the D3 ecosystem. It enables the creation of custom map projections that require precise spherical clipping, such as polyhedral, interrupted, and complex logarithmic projections. The module provides essential tools for advanced cartographic visualizations where standard projections are insufficient.
Data visualization developers and cartographers working with D3 who need to implement custom or specialized map projections requiring spherical polygon clipping. It's particularly useful for those creating educational, scientific, or artistic geographic visualizations.
Developers choose d3-geo-polygon because it provides mathematically rigorous spherical clipping operations that are essential for implementing complex map projections within D3. It offers unique projections not available in standard libraries and gives fine-grained control over clipping behavior for both aesthetic and functional requirements.
