This example shows a Lambert conformal conic projection of the world map, rendered from TopoJSON data. The map displays country outlines as a single land layer. The visualization uses the d3.v3 library, specifically the `d3.geo.path()` function with a `null` projection, to draw the projected paths onto an SVG canvas. The TopoJSON data is loaded from `world.json` and converted to features using `topojson.feature` before being inserted into the scene.
