d3-geo-polygon

What's Changed

• Adds two new projections based on the Voronoi polyhedral method: Rhombic dodecahedral and Deltoidal hexecontahedral, contributed by @bathoorn (#59 and #60)
• A polyhedral projection’s tree can now be built from any face (#63)
• The module now reexports all the projections from d3-geo-projection that need polygon clipping (#65, #69), namely: geoBerghaus, geoGingery, geoHealpix, geoInterruptedBoggs, geoInterruptedHomolosine, geoInterruptedMollweide, geoInterruptedMollweideHemispheres, geoInterruptedSinuMollweide, geoInterruptedSinusoidal, geoTwoPointEquidistant, geoTwoPointEquidistantUsa, and the geoInterrupt projection factory.
• A new clipPoint option for geoClipPolygon, specifying whether points should be clipped (#67)
• Adopt type: module (#61)

Full Changelog: https://github.com/d3/d3-geo-polygon/compare/v1.12.1...v2.0.0-alpha.1

• upgrade dependencies (node, canvas 1-2, d3-geo 1-2)

• Cahill-Keyes inverse (using the Newton 2D method)

• adds projection.reflectX (cf. d3-geo 1.12)

• fix clipping errors (#30)

• better convergence of geoTetrahedralLee’s inverse ("backtrack if overshooting")

• inverse of d3.geoTetrahedralLee ; see https://observablehq.com/@fil/tetrahedral-lee-inverse for details.

• Adds the d3.geoComplexLog projection (thanks, @biosmanager and @grtlr !)
  

• fix Cox projection (https://github.com/d3/d3-geo-polygon/commit/6f9f9c7c844ac0f5da747e645951f643bf08d835)
• Mark the package as having no side effects (thanks, @stof !)
• Relax d3-array dependency to 1-2

• Fix Lee’s tetrahedral South aspect #28

  See https://github.com/d3/d3-geo/issues/160 & https://observablehq.com/@fil/d3-geointersectarc

Adds the Imago projection, engineered by Justin Kunimune (2017), and inspired by Hajime Narukawa’s AuthaGraph design (1999). Thank you, @jkunimune15 !
