A D3.js library that morphs GeoJSON polygons into rectangular shapes for cartographic visualization.
d3.geo2rect is a D3.js extension library that morphs GeoJSON polygon data into rectangular shapes for alternative cartographic visualizations. It transforms geographic regions into grid-aligned rectangles while maintaining their spatial relationships through animated transitions. The library helps create unique map representations that balance geographic accuracy with visual organization.
Data visualization developers and cartographers working with D3.js who need to create alternative geographic representations or grid-based maps with smooth transitions between views.
Developers choose d3.geo2rect for its specialized ability to create morphing animations between geographic polygons and rectangles, offering a unique approach to cartographic visualization that standard mapping libraries don't provide.

Enables configurable animated transitions between geographic and rectangular views, with a duration setting and toggle functionality demonstrated in the examples.
Simplifies input data by converting MultiPolygons to single polygons and removing holes, making it easier to process for rectangular transformations.
Allows manual grid positioning of rectangles via config settings, providing flexibility for organized spatial arrangements, though it lacks automatic computation.
Works directly with D3.js for rendering and animation, leveraging existing D3 workflows and tools for map visualization.
Requires explicit grid mapping for each region, as admitted in the README, which can be tedious and error-prone for large datasets.
Loses geometric detail by removing holes and reducing MultiPolygons, limiting its use for applications needing full GeoJSON fidelity.
Depends on D3.js and turf.js, increasing bundle size and setup complexity for projects not already using these libraries.
