{"version":"1.0","type":"rich","title":"Misplaced line simplification","description":"This animation demonstrates why line simplification should be performed before projection, not after. A graticule and a spiral path are rendered through five projection stages—conic conformal, spiral interpolation, orthographic, and more—using D3’s geo path and tweened transitions. As the projections morph and spin, a simplification algorithm is applied to the spiral's coordinates at certain stages, causing visible geometric distortion and discontinuities that highlight the risks of simplifying lines in projected space. The visualization uses SVG with animated transitions and colored graticules to illustrate the time periods and the misplaced simplification artifacts.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-0cf5238bb2b3152549e2b0b33c44b663?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
