-# Changed
+### Added

+- feat: Support for providing lon/lat coordinates from a text file (loaded with numpy loadtxt method) to build the graph `TextNodes` (#93)
+- feat: Build 2D graphs with `Voronoi` in case `SphericalVoronoi` does not work well/is an overkill (LAM). Set `flat=true` in the nodes attributes to compute area weight using Voronoi with a qhull options preventing the empty region creation (#93) 
+- feat: Support for defining nodes from lat& lon NumPy arrays (#98)
+- feat: new transform functions to map from sin&cos values to latlon (#98)

 - fix: faster edge builder for tri icosahedron. (#92)
