This interactive visualization demonstrates dynamic line simplification on a world map, where the level of detail adjusts as the user zooms in and out. It renders an orthographic projection of world country boundaries using the D3 `geoOrthographic` and `geoPath` APIs onto a Canvas, with data from the visionscarto-world-atlas. The code leverages `topojson-simplify` to recompute simplified geometries based on the current zoom scale, showing a proof-of-concept for performance-adaptive map rendering.
